Various anomalies for the origin of the middle meningeal artery (MMA)have been described in the literature. However, origin of the MMA fromthe basilar trunk is an extremely rare variant. We report on a 54-year-oldfemale who presented with frequent headaches; magnetic resonanceimaging showed a right parietal meningioma. The abnormal origin of themiddle meningeal artery from the basilar artery was diagnosed by angiographyperformed for preoperative embolization of the tumor. We reporton the case with a review of the embryologic basis, possible explanationsfor this aberrant origin, and its clinical implications.
