[Pediatric Posterior Fossa Tumors].

ABSTRACT

Posterior fossa tumors tend to entail obstructive hydrocephalus, and urges initiating prompt treatment. Prevalent pathologies include medulloblastoma, ependymoma, pilocytic astrocytoma, and atypical teratoid/rhabdoid tumor(AT/RT). In most cases, maximal safe resection is related to better prognosis. In some cases of ependymoma and AT/RT with high vascularity, second-look surgery with neoadjuvant chemotherapy is effective. The treatment strategy should be tailored according to each tumor.
