Meningioma is a benign tumor developing in the meningeal layers. Extracranial meningiomas, seven cases of which are reviewed, are often revealed by ENT signs. In the majority of cases they originate from the cranium and histologic diagnosis (particularly of fresh specimens) is often difficult. A CT scan is the examination of choice for assessing possible extension of these tumors. Treatment often involves the combined efforts of a neurosurgical and an otorhinolaryngologic team.
