title: Extracranial and intracranial meningiomas.
abstract: Meningiomas constitute about 18% of primary intracranial tumors, and they are rarely observed in patients under 30 years of age. In this study, we present the case of a 17-year-old patient who was first seen for a right cervical mass. Further investigation revealed that a meningioma of the posterior cranial fossa had invaded the temporal bone, the infratemporal fossa and the right parapharyngeal region and was at the origin of that cervical mass. This intra- and extracranial meningioma was completely resected in two stages with very satisfactory results. We have reviewed the literature pertaining to the extracranial extensions of meningiomas originating in the posterior fossa.
