introduction: to report our experience with a large series of surgical procedures for removal of cerebellopontine angle (cpa) tumors using different approaches.   materials and methods: this was a retrospective analysis of 50 patients (mean age, 49 years) with cpa tumors (predominantly acoustic neuroma) who underwent surgical removal using appropriate techniques (principally a translabyrinthine...

BACKGROUND Though the classical type of trigeminal neuralgia is the most common type with the neurovascular conflict causing the symptoms, yet quite some patients have the secondary type of trigeminal neuralgia in which space occupying lesions are responsible for the symptoms. This study was conducted to determine the frequency of cerebellopontine angle tumours in patients presenting with compl...

OBJECTIVES Non-acoustic tumours of the cerebellopontine angle differ from vestibular schwannomas in their prevalence, clinical features, operative management, and surgical outcome. These features were studied in patients presenting to the regional neuro-otological unit. METHODS A retrospective analysis of clinical notes identified 42 patients with non-acoustic tumours of the cerebellopontine ...

Cerebellopontine angle (CPA) tumours are the most common neoplasms in the posterior fossa, accounting for 5-10% of intracranial tumours. Most CPA tumours are benign, with most being vestibular schwannomas. Meningiomas arising from the jugular foramen are among the rarest of all with very few being described in the literature. Treatment options vary considerably as experience with these tumours ...

Glomus tumours involving the middle ear and the cerebellopontine angle are reported with emphasis on audiological findings. Magnetic resonance imaging (MRI), angiographic and pathological results are presented. Audiological tests, including impedance audiometry, evoked otoacoustic emissions and auditory brainstem responses, are valuable in evaluation of the effect of glomus tumours on the audit...

Tumours of the cerebellopontine angle (CPA) account for 5% to 10% of all intracranial neoplasms. Various surgical approaches are possible for providing access to tumours of the CPA. The retrosigmoid approach to the posterior cranial fossa is the latest of numerous modifications of the classic suboccipital approach originally popularized by Harvey Cushing. The aim of this review is to discuss th...

Ependymomas are relatively rare glial neoplasms that arise from ependymal cells. The majority of cases (>75%) arise from the fourth ventricle in the posterior fossa. These tumours may expand locally, extend along subarachnoid spaces, and disseminate through the cerebrospinal fluid. Sometimes, they may extend into the cerebellopontine angle and mimic the clinicoradiological appearance of an extr...

OBJECTIVE To assess the diagnostic efficiency and costs of protocols used for investigating patients with suspected lesions of the cerebellopontine angle. DESIGN Prospective evaluation of tests of auditory brain stem responses and acoustic reflex thresholds, electronystagmography, and calorics. Positive test results were confirmed or refuted by high resolution computed tomography with intrave...
