There are numerous (>20) bilateral periventricular and subcortical white matter T2/FLAIR hyperintense lesions with morphology and distribution consistent with known demyelinating disease. There are confluent areas noted in the periventricular distribution. There are also a few T1 hypointense lesions. There is mild posterior fossa involvement including the bilateral middle cerebellar peduncles. Parenchymal volume is grossly maintained.There is no evidence of intracranial mass. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Moderate burden of T2/FLAIR hyperintense lesions related to known demyelinating disease. No prior studies are available for comparison; an addendum can be issued if they are made available.
