Posterior fossa chondroma arising from the tentorium: a case report

Abstract

Intracranial chondroma is a rare tumor with an estimated incidence of 0.1–0.2 percent of all intracranial tumors [9]. The most common site of origin is the synchondrosis of the skull base. Some authors have reported intracerebral [2] or meningeal chondroma [1,3,8,14,15]. However, posterior fossa chondroma arising from the tentorium is rare. Here we report a case of a tentorial chondroma in the posterior fossa.
