Multiple sclerosis. Follow-up progression. There are numerous periventricular and subcortical FLAIR hyperintense lesions, as well as additional lesions within the brainstem and cerebellum. There is no significant interval change. There is no evidence of intracranial hemorrhage. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. A cavum septum pellucidum et vergae is incidentally noted, a normal variant.
No significant interval change in numerous FLAIR hyperintense lesions, consistent with history of multiple sclerosis.
