Middle Meningeal Artery Originating from the Basilar Artery: Neuroimage

The middle meningeal artery (MMA) supplies over two-thirds of the cranial dura mater, making its anatomical knowledge crucial for surgery. Rarely, the MMA may originate from the basilar artery. Typically, it arises between the superior cerebellar artery and anterior inferior cerebellar artery, following a course near the trigeminal nerve to reach the petrous branch of the MMA. An embryological origin involves anastomosis between persistent stapedial and trigeminal arteries. The image illustrates an unusual case of a patient with right MMA originating from the posterior circulation via the basilar artery.
