FIG 3. On axial T2-weighted (A) and contrast-enhanced (B) MR images, repeat MR imaging shows marked enlargement of the previously noted cystic lesions in the basal ganglia and florid peripheral postcontrast enhancement of the lesions. New areas of restricted diffusion are seen on the diffusion-weighted (C) and the apparent diffusion coefficient map (D) images, which are different in location from those seen before.
