 There are numerous T2 hyperintense lesions involving the cerebral white matter. A few lesions have increased in size, particularly in the bilateral deep anterior frontal lobe white matter and septocallosal region. Many lesions demonstrate corresponding T1 hypointensity. The ventricles and cortical sulci are mildly prominent diffusely due to cerebral volume loss. 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.
Numerous supratentorial demyelinating lesions, some of which appear to have slightly increased in size.
