Multiple sclerosis: ataxia, weakness. Brain: There appear to be postoperative findings related to left transfrontal biopsy. There are extensive supratentorial and infratentorial T2 hyperintense lesions, many of which are T1 hypointense as well. There also appear to be T2 hyperintense lesions involving the bilateral optic nerves. There is a small area of encephalomalacia in the right external capsule. There is no evidence of intracranial mass. There is no midline shift or herniation. The major cerebral flow voids are intact. Cervical Spine: There are multiple T2 hyperintense lesions in the imaged portions of the spinal cord. There is reversal of the usual cervical lordosis, but no spondylolisthesis. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The paravertebral soft tissues are unremarkable.
1. Extensive intracranial and spinal demyelinating lesions related to multiple sclerosis, as well as possible optic nerve lesions.2. Apparent right external capsule chronic lacunar infarct.
