Rare Arterial Anomalies: Bilateral Posterior Inferior Cerebellar Artery Originating from the Posterior Meningeal Artery and Anterior Inferior Cerebellar Artery-posterior Inferior Cerebellar Artery Anastomosis. [PDF]

NMC Case Rep J
Variations in the posterior inferior cerebellar artery are well-documented. However, bilateral posterior inferior cerebellar artery originating from the posterior meningeal artery is extremely rare, and no such cases have been previously reported. Anastomosis between the anterior inferior cerebellar artery and posterior inferior cerebellar artery is a ...
