Hemangiomas of the internal auditory canal.
Three patients who presented with symptoms and signs of acoustic tumors are described: one of them had an arteriovenous malformation and the other two had cavernous hemangiomas. The common feature in all these patients was the presence of marked facial weakness with or without fasciculations and a complete loss of hearing in the presence of a small tumor. The cerebrospinal fluid protein was normal in these patients. Polytomography and Pantopaque cisternograms were used to make the diagnosis. Since these lesions are circumscribed, they are suitable for removal using microneurosurgical techniques.
