 There has been interval decrease in size of the dominant left temporoparietal lesion, now measuring up to are approximately 15 mm. Otherwise, there is no significant interval change in the multiple smaller periventricular and pericallosal T2 hyperintense white matter lesions, accounting for differences in technique. There is no evidence of acute hemorrhage or infarction. The ventricles and sulci are within normal limits. There is no midline shift or mass effect. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Interval decrease in size of the tumefactive demyelinating lesion in the left temporoparietal region. Otherwise, no significant interval change in the intracranial demyelinating lesions.
