title: [Tumors of the posterior cranial fossa].
abstract: Various types of brain tumor can occur in the region of the posterior fossa. Brain metastases in adults are the most common malignancies at this localization. Ependymomas, medulloblastomas and pilocytic astrocytomas occur mostly in children and only rarely in adults. Other tumors that occur in the posterior fossa are meningiomas, schwannomas, hemangioblastomas, brain stem gliomas and epidermoid tumors. Due to the fact that the various tumors of the posterior fossa have different treatment approaches and prognoses, an accurate and specific diagnosis is mandatory. This review discusses the imaging aspects by computed tomography (CT) and magnetic resonance imaging (MRI) of the most frequent tumors of the posterior fossa.
