Increasing experience with selective cerebral arteriography in the diagnostic evaluation of acoustic tumors has led to a more rational determination of the proper surgical approach to the lesion. It also predicts the necessity for staging the surgical procedure, reduces the potential for intraoperative complications and rules out other types of angle lesions and the possible necessity for performing a preoperative, concomitant or postoperative shunting procedure. The CAT scan has added an important screening procedure in predicting the presence of an angle lesion, determining the need for further diagnostic studies and evaluating the possible presence or absence of a recurrent tumor growth.
