Glioblastoma of the cerebellum. A report of 3 cases.

Glioblastoma (GBM) is one of the commonest intra cranial tumors. Infratentorial GBM is, however, a rare entity. We report 3 cases of histologically proven posterior fossa GBM. The clinical presentation was of a rapidly growing posterior fossa mass. The diagnosis was made only on histological examination. The radiological features are non-specific and the clinical course same as GBM elsewhere. We describe their clinical presentation, radiological and pathological features and a review of describe the literature.
