43-year-old female with multiple sclerosis. F/u progression. Again seen are new numerous T2/FLAIR hyperintense lesions predominantly within the supratentorial white matter and including the periaqueductal gray, which appear similar to the previous exam allowing for differences in technique. These lesions are T1 hypointense with some markedly T1 hypointense. There is no evidence of intracranial hemorrhage, mass, midline shift or herniation. The ventricles and basal cisterns are unchanged in size and configuration. The skull and extracranial soft tissues are unremarkable. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Allowing for differences in technique, the numerous white matter lesions in the brain compatible with multiple sclerosis are not significantly changed.
