Common symptoms of spinal cord compression include: Balance issues. Know what to expect if you do not take the medicine or have the test or procedure. Your spinal cord is a bundle of nerves that runs down the middle of your back. The spinal nerves below the level of injury get signals, but they are not able to go up the spinal tracts to the brain. You must be logged in to reply to this topic. 2019 Sep 3;9(9):e029153. My lumbar spine shows a "protruding L5-S1 disc in a central right paramedian position most suggestive of a small annular tear. Cervical (neck) spinal cord T2/FLAIR lesions could cause tingling and numbness in the hands and legs. Thank you for choosing Dr. Corenman as your healthcare provider. They're used to treat many forms of chronic pain, including back pain after failed surgery. Figure 2a. Together, the brain and spinal cord are known as the central nervous system (CNS). Laboratory tests in patients with NMOSD are likely to show the presence of the NMO-IgG antibody, a serum autoantibody that reacts to the water channel protein aquaporin-4. Karpova A, Arun R, Cadotte DW, Davis AM, Kulkarni AV, O'Higgins M, Fehlings MG. Spine (Phila Pa 1976). A study published in the Journal of Neurophysiology claims that injuries associated with the spinal cord (SCI), that often result in nerve damage, can now be reversed using peripheral nerve stimulation. Nonetheless, imaging of the cord in suspected ALS can help confirm the diagnosis, exclude other causes, and monitor progression (50,51). (b) Axial T2-weighted MR image shows that the cord appears to be apposed to the ventral aspect of the dura with no visible CSF ventral to the spinal cord (arrow). MRI of the brain as well as the spinal cord is essential and may further help distinguish ADEM from MS. Intracranial findings may mimic MS, but certain features help confirm the diagnosis of ADEM, such as the presence of larger lesions in the subcortical white matter, involvement of the deep gray matter structure (basal ganglia and thalami) and brainstem, and relative sparing of the periventricular region (14,16) (Fig 6). Figure 9a. If the diagnosis is still uncertain after spinal imaging and clinical workup, additional imaging of the brain may be helpful. Ventral refers.

Hohenhaus M, Egger K, Klingler JH, Hubbe U, Reisert M, Wolf K. BMJ Open. Biomed Res Int. (d) Axial CT myelogram at the T3-T4 level demonstrates the center of the cord possibly extending through the anterior surface of the dural sac (arrow). What is a signal cord? The combination of clinical history and imaging findings is typical of radiation myelopathy. Intraoperatively, this was confirmed to be a ventral thoracic dural defect causing spinal cord herniation. A short T2 means that the signal decays very rapidly. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username. Figure 7d. For these, please consult a doctor (virtually or in person). (c) Sagittal CT myelogram shows a ventrally displaced spinal cord that is closely apposed to the dorsal aspect of the vertebral bodies throughout the thoracic spine (arrowheads), with focal distortion of the posterior cord contour at the T3-T4 level with a transition in the cord caliber (arrow). (a, b) Images in a 50-year-old man with progressive spastic quadriplegia show diffuse cord atrophy through visualized segments of the cervical and upper thoracic spinal cord (a) with subtle T2 SI involving the central portion of the spinal cord (arrowhead in b). ? Contrast with the power cable, which provides electricity to the unit. They also hold your body upright. Copyright 2023 WisdomAnswer | All rights reserved. Of particular note, Gibbs artifact can appear as alternating lines of low and high SI extending along the long axis of the spinal cord, which can mimic a cord SI abnormality or a syrinx (3) (Fig 2). These terms are often confused because both conditions result in high T2 signal in the cord and reduced cord size. Other Abnormalities.Rare anatomic abnormalities such as spinal cord herniation and arachnoid webs can be seen at imaging as intramedullary T2 hyperintensity and may progress to syrinx formation secondary to a disruption of CSF flow dynamics (61). Most MRI reports are black and white with shades of gray. (b) On an axial T2-weighted MR image, the lesion is seen to affect nearly the entire cross-sectional volume of the spinal cord without associated expansion (arrow). Spinal cord injuries are traumatic for patients and their families. What next . Clinical Features of Demyelinating Diseases. Other procedures may be done to relieve pressure on the spine or repair fractured vertebrae. Arachnoid web in a 47-year-old man with a history of progressive paraparesis and lower extremity numbness. Narrowing, impression, and deformity mean the same as compression in this sense- something, most likely bulging or herniated discs are pressing on the spinal cord in neck. An increase in T2 signal intensity is often associated with chronic compression of the spinal cord, and it is well established that chronic compression results in structural changes to the spinal cord. Difficulties may occur with bladder and/or bowel control. Variable intramedullary enhancement can be seen in any of these conditions; however, neurosarcoidosis may have distinguishing features including dorsal spinal cord predominance, leptomeningeal enhancement, and the trident signcrescentic posterior subpial enhancement with subtle additional central canal enhancement (53,54) (Fig 15). Intraoperatively, this was confirmed to be related to arachnoiditis with webs without evidence of cord herniation. Except in cases of emergency, such as cauda equina syndrome or a broken back, surgery is usually the last resort. ADEM in a 10-year-old boy with acute onset of weakness. (d) Intraoperative image obtained during T8-T10 laminectomies demonstrates findings seen on the MR images and DSA image. (d) Axial CT myelogram at the T3-T4 level demonstrates the center of the cord possibly extending through the anterior surface of the dural sac (arrow). Spinal cord compression can occur anywhere from your neck (cervical spine) down to your lower back (lumbar spine). Sagittal STIR (a), T1-weighted (b), and contrast-enhanced T1-weighted (c) MR images demonstrate a heterogeneous mildly enhancing intramedullary lesion in the upper thoracic cord, causing cord expansion (arrow). Will you please tell me what all that means? The emergency department radiologist should be familiar with the common differential diagnoses of acute myelopathy and be able to differentiate compressive from noncompressive causes. The C2 - C3 junction of the spinal column is important, as this is where flexion and extension occur (flexion is the movement of the chin toward the chest and extension is the backward movement of the head). I dont have ED but usually can't "finish" sometimes I can with aggressive. Diffusion restriction can be a useful ancillary imaging feature, similar to in intracranial abscesses (41). 23,087 satisfied customers. If the address matches an existing account you will receive an email with instructions to reset your password. (c) Follow-up axial MR image 6 months later demonstrates complete resolution of the previously seen hyperintense lesion in the right thalamus. (a) On a sagittal STIR image, hyperintensity involving the dorsal aspect of the cord extends from C1 to C6 (arrow). 4.Neurons are brain cells. Put simply, a lesion is the name given to an abnormal change which occurs to any tissue or organ, caused by a disease or injury. What does this c-spine mri mean? The aim of this review is to summarise and discuss recent advances in spinal cord MRI. Posterior spinal artery infarct produces T2 hyperintensity that is limited to the dorsal columns and posterior horns (31,34). I. Occasionally, a spinal nerve root is subjected to compression or irritation due to several factors. 3. Degenerative diseases such as amyotrophic lateral sclerosis and spinal muscular atrophy. (c, d) Sagittal (c) and axial (d) contrast-enhanced MR images show associated dorsal pial enhancement (arrow) and enlarged mediastinal lymph nodes (arrowheads in d). Spinal cord compression can cause cauda equina syndrome, which needs medical attention right away. On 3/19/2014 I had an MRI as ordered by my primary care. Sagittal MR images show multiple alternating light and dark parallel lines (arrow) at high-contrast interfaces, mimicking intrinsic cord SI abnormality or a syrinx. The vacuolization within the white matter of the cord seen at histologic analysis can be seen at MRI as an area of symmetric nonenhancing high SI in the posterior columns. 1, 2023 Radiological Society of North America, Imaging approach to the cord T2 hyperintensity (myelopathy), Magnetic resonance imaging assessment of degenerative cervical myelopathy: a review of structural changes and measurement techniques, Pitfalls and artifacts encountered in clinical MR imaging of the spine, Compressive myelopathy: magnetic resonance imaging findings simulating idiopathic acute transverse myelopathy, Compressive myelopathy mimicking transverse myelitis, Spinal cord MRI in multiple sclerosis: diagnostic, prognostic and clinical value, Temporal trends in the incidence of multiple sclerosis: a systematic review, Diagnosis of multiple sclerosis: 2017 revisions of the McDonald criteria, Cerebrospinal fluid humoral immunity in the differential diagnosis of multiple sclerosis, Differential diagnosis of T2 hyperintense spinal cord lesions: part B, Grey matter pathology in multiple sclerosis, Acute disseminated encephalomyelitis in childhood: epidemiologic, clinical and laboratory features, Acute disseminated encephalomyelitis: current understanding and controversies, Acute disseminated encephalomyelitis in children: differential diagnosis from multiple sclerosis on the basis of clinical course, Imaging of acute disseminated encephalomyelitis, Spectrum of MRI brain lesion patterns in neuromyelitis optica spectrum disorder: a pictorial review, The incidence and prevalence of neuromyelitis optica: a systematic review, Comparison of clinical characteristics between neuromyelitis optica spectrum disorders with and without spinal cord atrophy, A serum autoantibody marker of neuromyelitis optica: distinction from multiple sclerosis, Cerebrospinal fluid findings in aquaporin-4 antibody positive neuromyelitis optica: results from 211 lumbar punctures, Neuromyelitis optica: clinical features, immunopathogenesis and treatment, Bright spotty lesions on spinal magnetic resonance imaging differentiate neuromyelitis optica from multiple sclerosis, Differentiating neuromyelitis optica from other causes of longitudinally extensive transverse myelitis on spinal magnetic resonance imaging, An approach to the diagnosis of acute transverse myelitis, Acute transverse myelitis: incidence and etiologic considerations, Diagnosis and differential diagnosis of acute transverse myelopathy: the role of neuroradiological investigations and review of the literature, Spinal cord ischemia: practical imaging tips, pearls, and pitfalls, Spinal cord ischemia: clinical and imaging patterns, pathogenesis, and outcomes in 27 patients, Posterior spinal cord infarction due to fibrocartilaginous embolization in a 16-year-old athlete, Spinal cord infarction: clinical and magnetic resonance imaging findings and short term outcome, Imaging Approach to Myelopathy: Acute, Subacute, and Chronic, Neuroimaging in acute transverse myelitis, Spinal cord infection: myelitis and abscess formation, Diffusion-weighted MR imaging of intramedullary spinal cord abscess, Neoplasms of the spinal cord and filum terminale: radiologic-pathologic correlation, Intramedullary Spinal Cord Tumors.

Know why a new medicine or treatment is prescribed, and how it will help you. The spinal cord is a main function cause it creates the pathway for the nerve impulses. dAVF in a 37-year-old man with a 4-month history of progressive lower extremity dysesthesias, gait unsteadiness, and weakness. You mention that there are a number of things that could cause abnormal signal. Clinical evaluation (including patient history, physical examination, and laboratory tests) is the cornerstone of workup of suspected spinal cord disease. The patients neurologic symptoms markedly improved after supplemental vitamin B12 injections. My Neuro symptoms improve when I have a CSF leak. Thanks. The three signals are: Sensory- signals that evoke feelings like temperature, touch, pain, and pressure. Neuromyelitis Optica Spectrum Disorder.NMOSD is a demyelinating disease that predominantly affects the optic nerves and spinal cord, although brain lesions appear to be more common than previously recognized (1,12,19). (b) Sagittal CT myelogram demonstrates relative expansion of the cord at the T4 level (arrow) with focal cord thinning at the T3-T4 level (arrowhead), corresponding to the cord abnormality seen on the MR image. Why are doctors able to reattach the nerves in a severed limb, but not a severed spinal cord? These joints, located between the pedicle and lamina on each side of the vertebral arch, are lined with smooth cartilage to enable limited movement between 2 vertebrae. What type of medicine do you put on a burn? (a) On a sagittal STIR image, hyperintensity involving the dorsal aspect of the cord extends from C1 to C6 (arrow). The cookies is used to store the user consent for the cookies in the category "Necessary". If the onset of symptoms is subacute or chronic, the next task is to examine the contour of the spinal cord to determine if the cord is focally expanded. As in infarction involving the brain, the onset of symptoms is abrupt and the neurologic deficits depend on the vascular territory and the level of cord affected (30). The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone). Advanced imaging techniques such as contrast-enhanced MR angiography or thin-section FIESTA (fast imaging employing steady-state acquisition) may serve as useful tools in indeterminate cases or for further characterization (38). It does not store any personal data. A mass can include a tumor or bone fragment. All responses are confidential. Presented as an education exhibit at the 2018 RSNA Annual Meeting. The anterior spinal artery perfuses the anterior two-thirds of the spinal cord, and the posterior spinal arteries supply the posterior one-third of the spinal cord. Clinical manifestation of intramedullary neoplasms typically involves insidious and progressive neurologic symptoms, with back or neck pain depending on the tumor location (43). Figure 16b. Paralysis. (a, b) Sagittal STIR image (a) and axial T2-weighted MR image (b) show extensive central T2 hyperintensity (arrow) without thoracic cord expansion in the prior radiation field. Spinal cord compression is caused by a condition that puts pressure on your spinal cord. A couple of points. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. (d) MR image shows mild expansion and patchy enhancement of the right optic nerve (arrowhead). Hemangioblastoma is a well-demarcated highly vascular nonglial tumor (42). my {young inexperienced pa} neurologist downplayed it? Sometimes, I go to take a step, and my leg just isnt there and I eat dirt/tile/carpet and maybe thats whats wrong with my right knee because its usually my right leg and I always land on my knee. When there are multiple lesions or additional lesions in the cerebellum, the diagnosis of von HippelLindau disease should be considered (42,43). MRI results: Spinal stenosis, cervical region and spondylosis without myelopathy or radiculopathy, cervical region. An increase in T2 signal intensity is often associated with chronic compression of the spinal cord, and it is well established that chronic compression results in structural changes to the spinal cord. Spinal cord ischemia can be arterial or venous. Figure 5b. Created for people with ongoing healthcare needs but benefits everyone. Figure 3b. Join our community today. Arachnoid webs are intradural extramedullary arachnoid tissue that crosses over the dorsal surface of the spinal cord (61). Figure 2. Such typical imaging findings in a patient with normal serum vitamin B12 levels should raise suspicion for alternate causes of SACD, such as nitrous oxide toxic effects, zinc toxic effects, or copper deficiency (4648). Our experts have collected everything in one place to help you learn more about your injury, locate doctors and treatment centers, find financial support, and get assistance navigating your next move. Because of the differing disease course and divergent therapeutic approach, it has become critical to differentiate NMOSD from MS when possible. What does this c-spine mri mean? (c, d) Sagittal (c) and axial (d) contrast-enhanced MR images show associated dorsal pial enhancement (arrow) and enlarged mediastinal lymph nodes (arrowheads in d). 6 Does the spinal cord send messeges to the brain? Acute Disseminated Encephalomyelitis.ADEM typically manifests as an acute monophasic illness after viral infection or vaccination, predominantly occurring in the pediatric population (1,14). Look at this map, it shows you where the nerves "hook" to in the skin. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up. Multiple falls can injure joints (knee pain). Owing to their infiltrative pattern of growth, they are typically poorly defined lesions with patchy enhancement and a large amount of peritumoral edema (42). The signal change in your spinal cord is something to pay attention to. Current treatments available for patients are: A spinal fracture may be remedied with surgery, but the abnormal movement of vertebrae or pieces of bone can cause a more severe spinal cord injury. Figure 5c. Find more COVID-19 testing locations on Maryland.gov. What should I do? Is the "front" of the spinal canal, in which the spinal cord and spinal nerves lie. During development, there's a disproportion between spinal cord growth and vertebral column growth. Cord ependymoma in a 25-year-old woman with a history of neurofibromatosis type 2 who presented with progressive back pain and leg numbness. Radiation myelopathy in a 63-year-old man with multiple myeloma who presented with progressive weakness and urinary retention approximately 6 months after targeted spinal radiation therapy. There is abnormal T2 hyperintensity involving the anterior horns of the central gray matter, demonstrating the owls eye sign (arrowhead in a), with a corresponding area of low SI on the ADC map (arrowhead in b and c), suggesting impeded diffusion from acute spinal cord infarction. At imaging, NMOSD lesions in the spinal cord are usually longer in craniocaudal extent than those in MS (>1.5 vertebral body) and involve the central gray matter of the cord, sometimes seen as longitudinally extensive spinal cord lesions (25) (Figs 4, 7). friend recommended waist trainer to help with posture and ease pain. You can help prevent symptoms of spinal cord compression caused by gradual wear and tear by keeping your back as strong and healthy as possible. However, you may visit "Cookie Settings" to provide a controlled consent. Know why a test or procedure is recommended and what the results could mean. The authors present an algorithmic approach to evaluating intrinsic abnormality of spinal cord signal intensity (SI), which incorporates clinical evaluation results, time of onset (acute vs nonacute), cord expansion, and pattern of T2 SI abnormality. Spinal cord and intracranial involvement in a 62-year-old woman with long-standing MS. (a, b) Sagittal STIR (a) and axial T2-weighted (b) MR images of the cervical and upper thoracic spine show areas of patchy and short-segment (<1.5 vertebral body length) hyperintensity with a peripheral wedge-shaped appearance (arrows). MS in the spinal cord commonly affects the cervical region (1). HHS Vulnerability Disclosure, Help Figure 14b. Imaging features can range from normal to diffuse T2 hyperintensity in the central spinal cord with associated cord atrophy (58) (Fig 17). One to two times per month, Virtual Advisors receive a link to short, interactive surveys. T2 hyperintensity can reflect many processes at the microscopic level, including edema, bloodspinal cord barrier breakdown, ischemia, myelomalacia, or cavitation (2). In chronic and long-standing or progressive disease, there can be spinal cord atrophy, which is thought to represent axonal loss (1,11). Mri findings say acquired spondylolisthesis and cervical spinal stenosis with myelopathy . The spinal cord is protected by the vertebrae. 8600 Rockville Pike Thecal refers to the covering of the spinal cord. I live in Florida and I have recently been deemed permanently disabled and for that reason, I cant get diagnosed or treated down here because Rick Scott is not a nice guy, which makes him a horrible governor for people like me, which is exactly why I am planning to move to Colorado in the next few months. Loss of bowel or bladder control. Figure 13a. Other conditions that may cause spinal cord compression can develop more quickly, even very suddenly, and can occur at any age: Symptoms of spinal cord compression can develop quickly or slowly, depending on the cause. Figure 10d. Results: In the initial phase, there may be a variable degree of enhancement. (a) Sagittal T2-weighted MR image shows a longitudinally extensive cord hyperintensity extending from the T9 level to the tip of the conus (arrow). Compromise of the anterior or posterior circulation causes different neurologic sequelae (30). Physical therapy is an important part of recovery to retain use of non-affected areas of the body as well as those directly affected by the damage done to the spinal cord. Recurrent idiopathic TM in a 60-year-old man with several weeks of worsening bilateral lower extremity weakness, pain, and numbness that progressed to an inability to walk. Having mild myelopathy. 26, No. (c) Axial contrast-enhanced T1-weighted MR image demonstrates mild patchy enhancement within the left hemicord (arrow). I have a question about an MRI report that shows some abnormalities. As such, abnormality of intramedullary signal intensity (SI) is somewhat nonspecific and can present a diagnostic dilemma. Figure 15d. Doc. The authors would like to thank Danielle Dobbs and Vanessa Allen for the illustrations. SACD in a 54-year-old man with progressive sensory and gait disturbance with mild cognitive slowing who was found to have a low serum vitamin B12 level. (c) Axial T2-weighted MR image in a different patient with suspected HIV myelopathy demonstrates hyperintensity in the dorsal columns (arrow), mimicking SACD. The brain is the bodys control centre. Astrocytoma, the most common glial tumor in the pediatric population, is an infiltrative glial tumor often involving multiple vertebral body levels of the cervical, thoracic, and sometimes the entire spinal cord (42,43). Contrast enhancement and cord expansion can be seen in an acute setting (1). The purpose of this study was to evaluate the effect of spinal cord T2 signal intensity changes on the outcome after surgery for CSM. Acute arterial compromise is often associated with plaque-related thrombosis or emboli. White matter disease is a disease that affects the nerves that link various parts of the brain to each other and to the spinal cord. Spondylotic compressive changes with myelomalacia. What causes spinal nerve impingement? Radiation myelopathy in a 63-year-old man with multiple myeloma who presented with progressive weakness and urinary retention approximately 6 months after targeted spinal radiation therapy. Neck or low back pain that radiates into your arms or legs is often a sign of impingement or pinching of a nerve as it emerges from your spinal cord. (c) Axial T2-weighted MR image shows hyperintensity (arrow) affecting more than two-thirds of the cross-sectional area of the cord. As the name implies, this syndrome is the result of damage to the central portion spinal cord and in the setting of trauma most commonly affects the cervical cord. (c) Follow-up axial MR image 6 months later demonstrates complete resolution of the previously seen hyperintense lesion in the right thalamus. I know your time is valuable and I appreciate anything you may be able to think of for me to have something to go on to look up. An increase in T2 signal intensity is often associated with chronic compression of the spinal cord, and it is well established that chronic compression results in structural changes to the spinal cord. (b, c) Additional axial MR images demonstrate T2 or FLAIR hyperintensity in the corticospinal tracts within the cerebral peduncles and lateral aspects of the midbrain and pons (arrows). These result in a cord contour distortion that appears similar to cord herniation (Fig 19). These bone growths, or spurs, can compress nerves. This is only causing slight flattening of . Many patients with MS have intracranial manifestations, so it is essential to evaluate for concomitant juxtacortical, periventricular, or infratentorial brain lesions (8) (Fig 5). I forget not only what I was saying in the middle of a sentence, but forget what the subject was. results says mild disc bulge that abuts the right ventral surface of the thecal sac. Pain and stiffness in the neck, back, or lower back, Burning pain that spreads to the arms, buttocks, or down into the legs (sciatica), Numbness, cramping, or weakness in the arms, hands, or legs, "Foot drop," weakness in a foot that causes a limp. The spinal cord sends the nerve impulses from the brain to the muscle faster than the blink of an eye. Pins and needles in hands and feet could originate from cord injury. Figure 7c. HIV Myelopathy.Despite widespread use of antiretroviral therapy, the incidence of neurologic sequelae in patients with HIV infection remains high at around 70% (57). The backbone encloses the central canal of the spinal cord, which contains cerebrospinal fluid.The brain and spinal cord together make up the central nervous system (CNS). Figure 5a. That out of the, way. Conclusion: Signal cable is used in data transmission applications that demand superior signal protection. The proposed mechanism is development of an autoimmune antibody against myelin basic protein (1). Maintain a healthy weight. Although the MRI was read as normal, it does not mean that you are without symptoms that may benefit from treatment. No statistically significant differences were found in recovery rates between cases with T2 signal intensity changes and those with no signal intensity changes. The .gov means its official. He was diagnosed with recurrent idiopathic TM after an extensive workup was negative for an alternate cause. Figure 14c. ALS is the most common type of motor neuron disease (49). The cookie is used to store the user consent for the cookies in the category "Performance". no masses are identified. In addition to multisystem disorders, post-treatment change after spinal irradiation can produce myelitis within the irradiated field (55). Spondylotic myelopathy in a 40-year-old man with leg weakness. (c) Image from digital subtraction angiography (DSA) helps confirm a type 1 spinal dAVF supplied by the left T9 segmental artery with drainage into the dilated and tortuous posterior coronal venous plexus. Viewing 6 posts - 1 through 6 (of 16 total). It contains tissues, fluids and nerve cells. At MRI, there is usually long-segment nonexpansile T2 hyperintensity, which can be seen in all three entities. On the contrary, hypointensity would be blacker in color. Therefore, this review focuses on intrinsic spinal cord SI abnormality that occurs in the absence of an extrinsic compressive lesion. Long-term surgical outcome and risk factors in patients with cervical myelopathy and a change in signal intensity of intramedullary spinal cord on Magnetic Resonance imaging. Medical care is focused on preventing further damage to the spinal cord and utilization of remaining function. (b) Sagittal CT myelogram demonstrates relative expansion of the cord at the T4 level (arrow) with focal cord thinning at the T3-T4 level (arrowhead), corresponding to the cord abnormality seen on the MR image. However, the acuity of symptoms helps determine the cause, which underscores the importance of the clinical evaluation. Signal change in the cord could be from mechanical injury (cord compression, arnold chiari syndrome), vascular changes (a stroke of the spinal cord), tumor (astrocytoma) or from autoimmune changes (multiple sclerosis). He was diagnosed with recurrent idiopathic TM after an extensive workup was negative for an alternate cause. (c) Axial fluid-attenuated inversion-recovery (FLAIR) MR image of the brain demonstrates areas of bilateral patchy T2 or FLAIR high SI in a pericallosal and periventricular distribution (arrows). What are symptoms of S1 nerve root damage? But the implications of .
