Bilateral lower extremity weakness since one week, upper extremity deltoid weakness, history of cancer The vertebral bodies are appropriate in the overall alignment and height. There is no evidence of cord compression or high-grade spinal canal stenosis in the cervical, thoracic, or lumbar spine.Degenerative changes are noted worst at the C4-C5 level with at least mild spinal canal stenosis at this level. Examination is inadequate to assess for cord signal abnormality at this level.There is subtle focal scalloping of the dorsal cord at the T3 level and focal anterior cord displacement. Mild degenerative changes are seen at multiple levels in the thoracolumbar spine. There is disk and endplate T2 hyperintensity at the T10-T11 level which is likely on a degenerative basis/Schmorl's node.
1. This is a limited exam specific for the exclusion of cord compression with additional axial T2 images of the upper thoracic cord. Due to the screening nature of this protocol details are not as evident on imaging as dedicated protocols of the spine. However, no cord compression or high grade spinal canal stenosis is identified.2. Dorsal scalloping of the thoracic cord at the T3 level and mild focal anterior displacement. Possibilities include arachnoid cyst versus transdural cord herniation. If patient has history of leptomeningeal disease, it is conceivable that this could be related to an adhesion. No cord signal abnormality is seen at this level. If clinically indicated, further evaluation of this area with myelogram can be considered. 3. Degenerative changes relatively worse at the C4-C5 level with at least mild spinal canal stenosis at this level related to disk osteophyte complex. Examination protocol is inadequate to assess for cord signal abnormality at this level.
