Radiographic anatomy of the accessory meningeal artery

Abstract

The accessory meningeal artery (AMA) was studied in 6 cadavers and correlated with the angiographic findings in 50 normal patients. The AMA is easily identified angiographically, its origin varying with the course of the internal maxillary artery. The authors believe that all intracranial lesions which are not strictly intracerebral should be investigated by means of selective injection of the internal maxillary artery.
