What Is a Spinal Lesion? I just dont understand why Im having all the symptoms Im having. The McDonald criteria are used to diagnose MS by incorporating clinical and radiologic evidence of multiple attacks disseminated in space and time (6,9). Wear and tear of the spine may take years to cause symptoms. The different types of signals are sent out and received in different ways. The authors present an algorithmic approach to evaluating intrinsic abnormality of . (a) Sagittal T2-weighted MR image demonstrates long-segment hyperintensity (arrows) extending from the upper to mid thoracic cord without expansion. Figure 15c. Our algorithmic approach that combines clinical evaluation, acute versus nonacute time of onset, cord expansion, and pattern of T2 SI abnormality provides a framework for radiologists to help narrow their differential diagnosis in imaging evaluation of myelopathy. (a, b) Sagittal T2-weighted MR images demonstrate longitudinally extensive abnormal T2 hyperintensity extending from the lower thoracic cord to the conus medullaris (arrow) with prominent surrounding flow voids (arrowheads). Know what to expect if you do not take the medicine or have the test or procedure. Acute arterial compromise is often associated with plaque-related thrombosis or emboli. The use of stem cells is seen more and more in research as these cells are specialized enough to possibly regenerate damaged spinal cord tissues. T2 reflects the length of time it takes for the MR signal to decay in the transverse plane. Risk Factors for Poor Prognosis of Spinal Cord Injury without Radiographic Abnormality Associated with Cervical Ossification of the Posterior Longitudinal Ligament. (c) Follow-up MR image 14 months after posterior decompression surgery demonstrates significant improvement of the cord edema with residual focal myelomalacia (arrow). So substances with short T2s have smaller signals and appear darker than substances with longer T2 values. The proposed mechanism is development of an autoimmune antibody against myelin basic protein (1). Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. They include neoplastic, metabolic, neurodegenerative, and inflammatory or immune-mediated disease and human immunodeficiency virus (HIV) infection. Figure 11. Restricted diffusion at diffusion-weighted imaging can improve diagnostic certainty when cord infarct is suspected (Fig 9) (35,36). While extremely rare, progressive cases of . (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). In chronic and long-standing or progressive disease, there can be spinal cord atrophy, which is thought to represent axonal loss (1,11). The back may also be stabilized by fusing some of the vertebrae together. ADEM can be differentiated clinically from MS by its monophasic course, signs of encephalopathy, and CSF analysis showing pleocytosis without oligoclonal bands (16) (Table). (c) Axial contrast-enhanced T1-weighted MR image demonstrates mild patchy enhancement within the left hemicord (arrow). Does no abnormal spinal cord signal mean no Myelopathy? But the implications of . All three vertebrae work together to support the neck and head. Neurosarcoidosis in a 52-year-old man with lower extremity weakness and fecal and urinary retention. Ependymoma is usually centrally located, enhances avidly, and commonly demonstrates peritumoral cystic change and hemorrhage (42). 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. Figure 14b. The brain stem collects the nerve messages and sends them as well. I have a question about an MRI report that shows some abnormalities. What does high signal in spinal cord mean? Bethesda, MD 20894, Web Policies Call your doctor or 911 if you think you may have a medical emergency. If the spinal canal is reduced between 10mm and 13mm in neutral position and in flexion the spinal cord is anteriorly displaced with CSF room posteriorly - could this cause myelopathy symptoms. Recognize pitfalls and mimics in evaluation of intrinsic spinal cord SI abnormalities, including those related to artifacts or extrinsic compression. (a) On a sagittal STIR image, hyperintensity involving the dorsal aspect of the cord extends from C1 to C6 (arrow). 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. The purpose of this study was to evaluate the effect of spinal cord T2 signal intensity changes on the outcome . However, the prognostic significance of signal intensity changes remains controversial. your suggestion? Spinal cord compression can cause cauda equina syndrome, which needs medical attention right away. Once artifacts and extrinsic compression are excluded as possible causes of cord SI abnormality, the remaining cord SI alterations can be considered intrinsic to the spinal cord. Radiologists play a valuable role in helping narrow the differential diagnosis by integrating patient history and laboratory test results with key imaging characteristics. Cervical stenosis is one such degenerative condition that may affect the spinal cord and lead to compromised coordination of the extremities. C2-C3: There is a mild right C3 foraminal narrowing. CSC is thought to represent pathological changes in the spinal cord detectable with histology that occur as a result of chronic compression 4). Intramedullary cord hyperintensity at T2-weighted MRI is a common imaging feature of disease in the spinal cord, but it is nonspecific. 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). The nerves are divided into five main sections (from top to bottom): cervical, thoracic, lumbar . The spinal cord is affected in more than 90% of patients with clinically definite MS, and up to 20% of patients will have only spinal cord manifestations (11). The aging process results in degenerative changes in the cervical spine that, in advanced . However, findings at MRI are often nonspecific and can vary significantly in patients with a clinical diagnosis of HIV myelopathy, likely owing to the heterogeneous nature of this disease entity. Clinical evaluation (including patient history, physical examination, and laboratory tests) is the cornerstone of workup of suspected spinal cord disease. The combination of clinical history and imaging findings is typical of radiation myelopathy. Figure 5a. They're used to treat many forms of chronic pain, including back pain after failed surgery.

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. The dilated perimedullary vessels manifest as multiple serpentine flow voids along the surface of the spinal cord (1,37) (Fig 10). I highly recommend Dr. Corenman and the Steadman Clinic. If cervical stenosis with myelopathy continues to progress and further compresses the spinal cord, severe symptoms can eventually develop in the latter stages. 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. The degree of spinal cord atrophy, especially gray matter, correlates with the degree of disability at both baseline and follow-up examinations (51). The combination of clinical history and imaging findings is typical of radiation myelopathy. (d) MR image shows mild expansion and patchy enhancement of the right optic nerve (arrowhead).

Your spinal cord is the bundle of nerves that carries messages back and forth from your brain to your muscles and other soft tissues. 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). 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). Rather than presenting an exhaustive list of spinal cord diseases, we focus on the common intrinsic disorders of the spinal cord with special attention to demyelinating conditions. Figure 9c. For potential or actual medical emergencies, immediately call 911 or your local emergency service. The occurrence of acute myelopathy in a nontrauma setting constitutes a medical emergency for which spinal MRI is frequently ordered as the first step in the patient's workup. a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue.

(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). If uncertainty persists, short-term follow-up spinal imaging may be helpful, as persistence or enlargement of the spinal lesion indicates a neoplastic process. Central cord syndrome is the most common form of incomplete spinal cord injury characterized by impairment in the arms and hands and to a lesser extent in the legs. On basic MRI imaging, swelling is not that easy to detect; a doctor may look for a slight enlargement of the spinal cord or some signal change. Careers. The spinal cord acts as the bodys telephone system, relaying information from the brain to the rest of the body, and sending signals about the rest of the body to the brain. Some other treatments that may be helpful for some people include acupuncture and chiropractic care.
