Acoustic neurinoma with intratumoral bleeding.

ABSTRACT

The Authors present a case of acoustic neurinoma which has caused intratumoral bleeding. Although acoustic neurinomas are about 8-10% of all intracranial tumors there are only few cases about acoustic neurinomas causing hemorrhage. Pathologic changes of intratumoral vessels in tumors larger than 2 cm were considered to be a cause of the hemorrhage. This rare pathology must be remembered as one of the causes of the intracranial bleeding.
