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). My MRI report says; There is multilevel cervical spondylitic change with the central canal stenosis being greatest at the C3-4 and C4-5 levels. (a, b) Sagittal (a) and axial (b) T2-weighted MR images show extensive central T2 hyperintensity (arrows) without expansion extending from the cervicomedullary junction to the conus medullaris. (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). Depending on the severity of the damage to the spinal cord, the injury may be noted as complete or incomplete. (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). (c) Axial contrast-enhanced T1-weighted MR image demonstrates mild patchy enhancement within the left hemicord (arrow). 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 compression can occur anywhere from your neck (cervical spine) down to your lower back (lumbar spine). They also hold your body upright. Reflex- signals that cause involuntary movements. (c) Axial T2-weighted MR image in a different patient with suspected HIV myelopathy demonstrates hyperintensity in the dorsal columns (arrow), mimicking SACD.
