Meningioma

A rare, mostly benign, primary tumor of the meninges (arachnoid cap cells), usually located in the supratentorial compartment, commonly appearing in the sixth and seventh decade of life, clinically silent in most cases or causing hyperostosis close to the tumor and resulting in focal bulging and localized pain in less than 10% of cases. Additional features may include headache, seizures, gradual personality changes (apathy and dementia), anosmia, impaired vision, exophthalmos, hearing loss, ataxia, dysmetria, hypotonia, nystagmus, and rarely spontaneous bleeding.

	The strange association of pneumosinus dilatans and arachnoid cyst: case report and review of the literature.
	Martin AJ, Jarosz JM, Thomas NW. Acta Neurochir (Wien). 2001;143(2):197-201.
	Pneumosinus dilatans may be either idiopathic, a reaction to an adjacent meningioma, or an 'ex-vacuo' response to cerebral volume loss and intracranial hypotension.

	En bloc removal of large bilateral olfactory groove meningioma.
	Salibi BS, Myers WO, Gildersleeve JW. Surg Neurol. 1978;9(4):264-6.
	With careful pre-operative angiographic evaluation, reversible intra-operative external carotid occlusion, controlled hypotension, steroids, osmotic diuretics, and early control of nutrient arteries, the en bloc removal of a large bilateral olfactory groove meningioma is feasible in some instances.
