55 years, Female, memory loss, multiple sclerosis. Again seen are multiple T2/FLAIR hyperintense lesions throughout the bilateral cerebral hemisphere subcortical and periventricular white matter with appearance and distribution consistent with known chronic demyelinating disease. Multiple infratentorial lesions are also again seen. Compared to 6/14/2013, there is a new lesion involving the right middle cerebellar peduncle. Otherwise no other new lesions are appreciated. No lesions with enhancement are definitively appreciated on the axial post gadolinium sequences, with phase artifact extending through the right middle cerebellar peduncle lesion. Multiple lesions with T1 hypointensity again seen. Evidence of mild global parenchymal volume loss which is prominent for age again seen. No evidence of intracranial mass effect, midline shift, or herniation. No hydrocephalus or extra-axial collections. Calvarium and extracranial soft tissues are grossly unremarkable.
Multiple supratentorial and infratentorial lesions consistent with chronic demyelinating disease. Compared to 6/14/2013, there is a new lesion involving the right middle cerebellar peduncle. Otherwise no additional new lesions are appreciated. No lesions with enhancement to suggest active demyelination.
