38 years, Male, multiple sclerosis, follow-up for progression. Paresthesias. Again seen are multiple scattered punctate and linear foci of T2/FLAIR hyperintensity within the periventricular and juxtacortical white matter, some of which are oriented perpendicular to the long axis of the lateral ventricles. These are consistent with demyelinating lesions. Some of the lesions appear more conspicuous on prior study performed at 3 Tesla. No new lesions are seen. No definite posterior fossa lesions are identified. There is mild burden of T1 hypointense lesions. Brain parenchymal volume appears preserved.The ventricles and sulci are within normal limits. The basal cisterns remain patent. There is no midline shift or mass effect. No extra-axial fluid collection is identified. Incidental note is again made of a partially empty sella. There is mild to moderate mucosal thickening in the maxillary sinuses as well as mild ethmoid opacification.
No new lesions to suggest progression of demyelinating disease.
