Abstract

Meningiomas are extra-axial neoplasms representing 15 - 20% of primary intracranial neoplasms. Incidence peaks in patients aged 40 - 60 years, and they more commonly affect women than men. Most meningiomas arise from arachnoidal cells on the inner surface of the dura and they thefore grow inward toward the brain to form bulky intradural tumour masses. Most meningiomas are benign, but ~6% are atypical or aggressive, and 1 - 2% are frankly malignant. Common locations for meningiomas include the cerebral convexity, parasagittal region, sphenoid wing, olfactory groove, tuberculum sella, posterior fossa, and cavernous sinus.
