Anterior inferior cerebellar artery

The anterior inferior cerebellar artery is located in the cerebellum of the brain. It originates at the basilar artery of the brainstem. The inferior cerebellar artery branches into three vessels: the internal auditory branch, medial branch, and lateral branch. The anterior inferior cerebellar artery is one of three arteries that provide oxygenated blood to the cerebellum. The other arteries supplying the cerebellum include the superior cerebellar artery and the posterior inferior cerebellar artery. Regions served by the anterior inferior cerebellar artery include the internal acoustic meatus, biventral lobule, superior semilunar lobule, and inferior semilunar lobule. If the anterior inferior cerebellar artery becomes blocked, a stroke can occur. Symptoms of damage that occurs as a result of a blockage to this artery include vertigo, nausea, hearing loss, falling to one side, facial paralysis, and loss of feeling in portions of the face. In rare cases, an aneurysm can occur in the anterior inferior cerebellar artery. An aneurysm is a ballooning of the blood vessel, and can be fatal if it ruptures.
