SURGICAL RESULTS IN UNUSUAL CEREBELLOPONTINE ANGLE TUMORS

Vestibular schwannomas account for 84% of cerebellopontine angle (CPA) lesions. The remaining CPA tumours comprise a fascinating group of le sions which may present in a similar fashion. Fortunately, advances in neuroradiology have increased our diagnostic accuracy of these lesion s. This paper describes the surgical results of a series of 69 CPA les ions which were not vestibular schwannomas. The majority of these unus ual CPA tumours were meningiomas, cholesteatomas and neuromas of other cranial nerves in the posterior fossa.
