title: Participation of the external and internal carotid arteries in the blood supply of acoustic neurinomas.
abstract: Six cases of acoustic neurinoma are presented in which the tumor is supplied by branches of the external carotid artery, with or without supply from the internal carotid artery. A new angiographic protocol for the investigation of masses in the cerebellopontine angle is suggested. According to early results of the CT scan, acoustic neurinomas always appear to be hypervascular following the injection of contrast media.
