Multiple sclerosis. There are multiple, greater than 10, cerebral white matter lesions, predominantly at the callososeptal interfaces and centrum semiovale bilaterally. There is interval subsidence of the enhancement associated with some of the lesions. However, there appears to be a new punctate T2 hyperintense lesion in the right posterior frontal centrum semiovale. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Interval subsidence of enhancement associated with some of the demyelinating lesions, but newly apparent lesion in the right posterior frontal centrum semiovale.
