Abstract

Pediatric cerebellar tumors constitute a heterogeneous group of central nervous system neoplasms with very different imaging characteristic, spread patterns, and outcomes. At one end of the spectrum are the pilocytic astroctyomas which have very good prognosis following complete resection. At the other end are the medulloblastomas and atypical teratoid/rhabdoid tumors with relatively poor outcomes. Familiarity with imaging characteristics of these common neoplasms is important in performing the role of the pediatric neuroradiologist. Magnetic resonance spectroscopy and diffusion weighted imaging play important adjuncts to conventional imaging in the diagnosis and follow-up of these tumors.
