Anomalous origin of the middle meningeal artery from the basilar artery: a case report.
Anomalous courses, anastomoses, and origins of the middle meningeal artery have often been described in the literature; however origin from the basilar artery or its branches is exceedingly rare with only five previous reports. We describe a middle meningeal artery originating from a large lateral pontine branch of the basilar artery. The lateral pontine branch also supplied most of the cerebellar hemispheric territory normally vascularized by both the anterior inferior cerebellar artery and posterior inferior cerebellar artery. We discuss the anatomy and possible embryological development of middle meningeal origin from the basilar artery.
