The anterior inferior cerebellar artery AICA is one of three vessels that provides arterial blood supply to the cerebellum. Before cross-sectional imaging, the AICA along with venous displacement was used to identify posterior fossa intra- or extra-axial masses, especially at the CP angle.

The amount of tissue supplied by the AICA is variable, depending upon whether the PICA is more or less dominant, but usually includes the anteroinferior surface of the cerebellum, the flocculus, middle cerebellar peduncle and inferolateral portion of the pons.

Anterior inferior cerebellar artery
The anterior inferior cerebellar artery AICA is one of three pairs of arteries that supplies blood to the cerebellum. It arises from the basilar artery on each side at the level of the junction between the medulla oblongata and the pons in the brainstem. It has a variable course, passing backward to be distributed to the anterior part of the undersurface of the cerebellum, anastomosing with both the posterior inferior cerebellar PICA branch of the vertebral artery and the superior cerebellar artery. It also gives off the internal auditory or labyrinthine artery in most cases; however, the labyrinthine artery can less commonly emerge as a branch of the basilar artery. The amount of tissue supplied by the AICA is variable, depending upon whether the PICA is more or less dominant, but usually includes the anteroinferior surface of the cerebellum, the flocculus, middle cerebellar peduncle and inferolateral portion of the pons. The symptoms include sudden onset of vertigo and vomiting, nystagmus , dysarthria , falling to the side of the lesion due to damage to vestibular nuclei , and a variety of ipsilateral features including hemiataxia, loss of all modalities of sensation of the face due to damage to the principal sensory trigeminal nucleus , facial paralysis due to damage to the facial nucleus , and hearing loss and tinnitus due to damage to the cochlear nuclei.
