“…Other structures it supplies include the trigeminal ganglion, the facial nerve, and the tensor tympani muscle ( 3 , 4 ). In rare instances, the MMA may arise from the basilary artery instead, which would normally originate from the confluence of two vertebral arteries, giving rise to the posterior component of the circle of Willis (the posterior cerebellar arteries, the pontine arteries, the anterior inferior cerebellar arteries, and the superior cerebellar arteries) and supplying the contents of the posterior cranial fossa ( 5 – 7 ).…”

BackgroundAnomalous origin of the middle meningeal artery (MMA) from the basilar artery is a rare congenital neurological variant that has been detected in both children and adults with diagnoses ranging from intracranial haemorrhage to ependymoma. This review aims to investigate the anatomical course of an anomalous basilar-middle meningeal artery and its clinical presentation.MethodsA systematic search was performed in PubMed using the keywords (middle meningeal artery) and (basilar artery). Ninety-four papers were identified, of which seven were included. One paper was further identified through cross-referencing.ResultsThe average age of presentation was 43 years with a male predominance (7/9). In most cases, the MMA arose between the superior cerebellar artery and the anterior inferior cerebellar artery (8/9) (versus 1 case between the anterior inferior cerebellar artery and the posterior inferior cerebellar artery). The anomaly mostly presented on the left side (6/11), but was bilateral in one case. Most of the cases showed a pontine artery branching from the basilar artery arising 5 mm to 10 mm proximal to the superior cerebellar artery, which would then assume the trajectory of the MMA. In three cases, the vessel increased in calibre near the trigeminal ganglion. Foramen spinosum absence in the anomalous side was noted in 3/6 of the patients.ConclusionTo avoid unexpected complications during neurosurgical and neuroradiointerventional procedures, it is essential to have a clear understanding of the anomalous routes of the MMA. This is especially important when it proves to be the only available route for embolization.
