Pediatric posterior fossa tumor
Epidemiology
Approximately half of pediatric central nervous system tumors are located in the posterior fossa.
Pilocytic astrocytomas (PAs), medulloblastomas (MBs), and ependymomas are the most common posterior fossa tumors.
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 1).
