Multiple sclerosis: fatigue, ataxia, and visual changes. There are numerous, greater than 10, foci of supratentorial and infratentorial white matter T2 hyperintensity, many of which display corresponding T1 hypointensity, which appear unchanged in extent, accounting for differences in technique. There is no evidence of corresponding abnormal enhancement. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. 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.
No significant interval change in the extent of the demyelinating lesions and no evidence of active inflammation.
