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.
