Multiple sclerosis. There are numerous T2 hyperintense lesions in the supratentorial and infratentorial white matter. Many of the lesions demonstrate T1 hypointensity, but there is no abnormal intracranial enhancement. 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 intracranial demyelinating lesions.
