Abstract: 

In adults, the most common expansile "mass" lesion in the posterior fossa is a subacute stroke, whereas the most common neoplastic lesion in the posterior fossa is cerebellar metastasis (intra-axial) or vestibular schwannoma (extra-axial). Those diseases fall outside the scope of this article, which focuses on primary intra-axial tumors of the posterior fossa in adults. This category of tumors is uncommon and more frequently encountered in children. This article reviews tumors of the cerebellum, brainstem, and fourth ventricle that are seen in adult patients, following categories from the 2007 World Health Organization classification of central nervous system tumors.
