Posterior fossa is the most common site for brain tumors in the first decade of life. Tumors occurring in this area are usually of either neuronal or glial origin. The common tumors include pilocytic astrocytoma, medulloblastoma, ependymoma, brainstem glioma and rarely atypical rhabdoid teratoid tumors. These account for approximately 50 to 55% of all tumors found in childhood. Less frequently, hemangioblastomas, dermoids, or arachnoid cysts are also encountered. In the Indian subcontinent, tuberculoma is an important entity and must be considered in the differential diagnosis of posterior fosss masses in children.1
