متن کاملFrequency of cerebellopontine angle tumours in patients with trigeminal neuralgia. .
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...
متن کاملThe Retrosigmoid Suboccipital Approach to Tumours of the Cerebellopontine Angle
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...
متن کاملCerebellopontine angle tumours: radiologic-pathologic correlation and diagnostic difficulties.
A group of 119 cases of cerebellopontine angle (CPA) tumours was studied looking at the pathological composition, relative incidence of tumour types, their radiological features and the pathological-radiological correlations. Tumours with preoperative radiological diagnosis and verified pathologically were analyzed. Histopathologically the material consisted of 77 schwannomas and 42 non-acousti...
