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.

Cholesteatoma

Cholesteatoma is a benign but potentially destructive growth consisting of keratinizing epithelium located in the middle ear and/or mastoid process. In cholesteatoma, a skin cyst grows into the middle ear and mastoid. The cyst is not cancerous but can erode tissue and cause destruction of the ear.

	Pauci-symptomatic large epidermoid cyst of cerebellopontine angle: case report.
	Di Rienzo L, Artuso A, Lauriello M, Coen Tirelli G. Acta Otorhinolaryngol Ital. 2004;24(2):92-6.
	Acoustic neuroma account for 90% and meningioma for 5-10% of these tumours, while a small percentage of rare tumours exist, the most frequent being epidermoid cyst, also known as congenital cholesteatoma or keratoma.

	[An operative case of cholesterol granuloma of the petrous apex].
	Saino M, Kayama T, Kuroki A, Siraisi Y, Sato K, Nakai O. No Shinkei Geka. 1996;24(11):1041-4.
	The characteristic hyperintense appearance of cholesterol granuloma on T1- and T2-weighted MR images is very useful for differentiation from other lesions of the petrous apex and the cerebellopontine angle such as cholesteatoma, mucocele, chordoma, and meningioma.

	Case reports illustrate the diagnosis and surgical management of a variety of unusual neoplasms, including an extradural meningioma of the temporal bone and clivus, a low grade squamous cell carcinoma on the tegmen in a radical cavity, a large primary cholesteatoma, an osteoblastoma of the temporal and occipital bones, an XIth nerve neuroma in the jugular bulb area, and an osseous hemangioma involving the facial nerve at the geniculate ganglion.
