14 years, Male, with paresthesias and previous diagnosis of multiple sclerosis. Several foci of T2/FLAIR hyperintensity are again seen in the bilateral subcortical and periventricular white matter and corpus callosum. The T2/FLAIR hyperintensity has decreased in some of the lesions since 1/6/2016. New T2/FLAIR hyperintense lesions are noted including the juxtacortical white matter of the anterior cingulate gyrus in the left paramedian frontal lobe, right posterior limb of the internal capsule/lateral thalamus, left lateral midbrain/pons, and bilateral middle cerebral peduncles. No significant burden of T1 hypointense lesions is evident. No restricted diffusion. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
Scattered foci of T2/FLAIR hyperintense white matter lesions with morphology and distribution compatible with known demyelinating disease. There are at least 5 new lesions consistent with disease progression.
