===== Epidemiology =====

Approximately half of [[pediatric central nervous system tumor]]s are located in the [[posterior fossa]].

[[Pilocytic astrocytoma]]s (PAs), [[medulloblastoma]]s (MBs), and [[ependymoma]]s are the most common [[posterior fossa tumor]]s. 

High-grade gliomas, atypical teratoid/rhabdoid tumor, and choroid plexus papilloma of the fourth ventricle are less frequent.

Because of the different treatment options and variability in long-term outcome, an accurate and specific diagnosis is mandatory

posterior fossa tumors including review of the literature. J Magn
Reson Imaging 2012;35:32–47.)).
