43 years, Female, ataxia, progression of multiple sclerosis. Again seen are numerous T2/FLAIR hyperintense lesions in the supratentorial and infratentorial brain consistent with known demyelinating disease. Compared to 3/2/2015, there is a new lesion involving the left dorsal pons. No associated enhancement, or abnormal enhancement elsewhere in the brain. No additional new lesions are definitively appreciated. There is a moderate burden of T1 hypointense lesions throughout the brain. There is moderate degree of brain parenchymal volume loss including thinning of the corpus callosum, which is similar to prior.No evidence of intracranial mass effect, midline shift, or herniation. No hydrocephalus. Calvarium and extracranial soft tissues are grossly unremarkable. Lesion in the cervical cord at the C2 level is noted and was present previous.
Chronic demyelinating disease with numerous supra- and infratentorial lesions. There is a new lesion in the left dorsal pons compatible with progression when compared to prior exam from 3/2/2015. No lesions with enhancement to suggest active demyelination.
