Multiple sclerosis: weakness. There is no significant interval change in the extent of the supratentorial and infratentorial white matter lesions. Many of the lesions demonstrate T1 hypointensity, but no abnormal enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a right maxillary sinus retention cyst.
No significant change in the intracranial demyelinating lesions.
