38 years, Female, facial twitching. Again seen are numerous periventricular and subcortical white matter T2/FLAIR hyperintense lesions in both hemispheres of the brain. Multiple infratentorial lesions including the brainstem, middle cerebellar peduncles, and cerebellar hemispheres are also again seen. Extent of confluent signal abnormality may limit detection of small new lesions, but there are at least 2 new lesions including the right inferior aspect of the mid callosal body (axial series 401 image 59, sagittal series 301 image 100) as well as the left frontal corona radiata (axial series 401 image 55, sagittal series 301 image 71). Upper cervical lesions are again seen but not well assessed.There is mild to moderate degree of parenchymal volume loss with thinning of the corpus callosum. There is a moderate burden of T1 hypointense lesions. No intracranial mass effect, midline shift, or herniation. No hydrocephalus. Major flow-voids are preserved. Calvarium and extracranial soft tissues are grossly unremarkable.
Numerous chronic supratentorial and infratentorial demyelinating lesions with at least two new lesions since 11/9/2015 as described above.
