Change in the disc signal, or darkening of the signal, is associated with dehydration or loss of hydrogen ions within the disc. When there is persistent diagnostic uncertainty, CSF sampling can help distinguish these causes because each condition manifests with specific disease markers. Spinal cord stimulators are implanted devices that help block pain signals from your brain. This central portion of the spinal cord, which relates to the C4 vertebra, contains nerves that run to the diaphragm, which helps us breathe by contracting and pulling air into the lungs.

CSF oligoclonal IgG bands are usually absent (14,23) (Table). 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. This discussion focuses on imaging features of intramedullary lesions, which can manifest as focal T2 hyperintensity within the cord. First, the new onset left sided neck and arm pain different from the chronic pain certainly could be from the residual foraminal compression at C4-5 (C4-C5: There is postoperative change and there is a moderate to severe left C5 foraminal narrowing due to uncinate hypertrophy). Medical researchers are continuously looking into new drug therapies to help regain sensory and motor function. A short lesion is defined as less than 1.5 vertebral bodies in length, compared to a long lesion, which is greater than 1.5 vertebral bodies in length.
