O neurinoma do acústico (NA), também conhecido como schwannoma VIII nervo, representa, na literatura, cerca de 2-7% dos tumores intracranianos que acometem o ângulo pontocerebelar (APC). Epidemiologicamente, sabe-se a incidência anual novos casos população geral pode ser 10: 1.000.000, sendo esse número correspondente aos sintomáticos, embora estudos mostrem valor se mostra ainda maior devido a...

The delayed development of brain abscess associated with a retained intracranial foreign body is not rare and has been documented [1-5] . We report an unusual case of chronic granulomatous abscess in the cerebellopontine angle region secondary to retention of a cotton ball during surgery for an acoustic neurinoma 20 years earlier. We describe the computed tomographic (CT) findings and emphasize...

Forty-seven acoustic neurinoma tumours have been operated on in 46 patients in the years 1987-1989. This is a considerable increase over the prevalence in the preceding ten years. Twenty-six were classified as large tumours, 18 as medium and one was small. Surgical excision was complete in 16 and incomplete in 31 cases. Two patients died in the early postoperative period. Facial nerve function ...

Cranial pairs V, VII, IX, X, XI and XII act directly on speech production and swallowing and, when involved, may interfere in the patient’s life quality, especially the social, nutritional and pulmonar...
