Multiple sclerosis with left lower extremity weakness and diplopia. Brain: There are unchanged extensive supratentorial and infratentorial high T2 signal cerebral white matter lesions without definite associated enhancement. Many of there demonstrate low T1 signal. There are multiple punctate foci of susceptibility effect in the bilateral deep grey matter, brainstem, cerebellum that likely represent chronic microhemorrhage. There is no evidence of intracranial mass or acute infarct. The major intracranial flow voids are grossly intact. There is a left maxillary sinus retention cyst. The extracranial structures are otherwise unremarkable.
1. No significant interval change in the extensive supratentorial and infratentorial demyelinating lesions and no evidence of acute infarction.2. Multiple punctate foci of susceptibility effect in the bilateral deep grey matter, brainstem, cerebellum that likely represent chronic hypertensive microhemorrhage.
