Female, 44 years old, with multiple sclerosis, assess for progression. Accounting for differences in technique, numerous scattered small foci of parenchymal T2 hyperintensity show no significant change in size. There may be one small new lesion within the left splenium of the corpus callosum, but otherwise the number of lesions appears grossly unchanged as well. None of the lesions demonstrates evidence of pathologic enhancement. The lesions show at most mild to moderate T1 hypointensity. No evidence of parenchymal edema or mass effect is seen. Brain parenchymal volume is relatively preserved. Ventricular size and morphology are within normal limits.
