Medulloblastoma in adults, regarding a case

Abstract

Posterior fossa tumors are uncommon in adults: they represent 15% or 20% of all brain tumors. Medulloblastoma, which corresponds to this classification, occurs in less than 1% of cases, unlike pediatric population, in which it is the most common malignant brain tumor. The most frequent medulloblastoma sub-type in adults is the desmoplastic, whose characteristics are correlated to the findings in the imaging studies. We present the case of a female patient with a posterior fossa tumor whose anatomopathological result was medulloblastoma.
