Axial brain magnetic resonance imaging at the level of the cerebellum performed 6 weeks after initial consultation. A) Contrast-enhanced T1 weighted image showing several ring-enhancing lesions in the right cerebellar hemisphere and the right cerebellar peduncle. B) The corresponding fluid attenuation inversion recovery image illustrates the extensive perifocal edema exerting a severe mass effect through compression and displacement of the fourth ventricle with consecutive enlargement of the lateral ventricle.
