Bottom Line: However, origin of the MMA from the basilar trunk is an extremely rare variant.The abnormal origin of the middle meningeal artery from the basilar artery was diagnosed by angiography performed for preoperative embolization of the tumor.We report on the case with a review of the embryologic basis, possible explanations for this aberrant origin, and its clinical implications.

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

Lateral view of the left external carotid artery injection shows the superficial temporal artery (small arrows) with filling of the normal middle meningeal artery (large arrows, A). Lateral view of the right external carotid artery injection shows the superficial temporal artery (small arrows) with no evidence of the middle meningeal artery (B). No tumor blush was seen on either injection.

Figure 2: Lateral view of the left external carotid artery injection shows the superficial temporal artery (small arrows) with filling of the normal middle meningeal artery (large arrows, A). Lateral view of the right external carotid artery injection shows the superficial temporal artery (small arrows) with no evidence of the middle meningeal artery (B). No tumor blush was seen on either injection.

Mentions: Six-vessel conventional cerebral angiography was performed for possible pre-operative embolization of the tumor. Injection of the left external carotid artery (ECA) showed normal anatomy, origins and configuration of the left internal maxillary, MMA and accessory MMA without contributing feeders to the tumor (Fig. 2A). Injection of the right ECA showed that the right internal maxillary artery had a small accessory MMA but no MMA or tumor blush (Fig. 2B). Injection of the left vertebral artery showed a dominant left vertebral system with the MMA arising from the upper basilar trunk (Fig. 3). It provided some blood supply to the tumor; however, when weighed against its benefit, the risk of embolization via this route was deemed unsuitable.
