MR images of the posterior fossa demonstrate multifocal abnormalities involving both cerebellar hemispheres, particularly located around the dentate nuclei. These regions are bright on T2 and FLAIR (arrows in A and B), lack restricted diffusion (C), are hypointense on T1 (arrows in D), and demonstrate patchy enhancement on postcontrast T1 fat-saturated images (E). Similar patchy enhancement is also noted in the midbrain (dashed oval on F).
