Artery: Anterior inferior cerebellar artery

The three major arteries of the cerebellum: the SCA, AICA, and PICA. (Anterior inferior cerebellar artery is AICA.)

Diagram of the arterial circulation at the base of the brain (Anterior inferior cerebellar artery labeled at lower right).
Latin	a. cerebelli inferior anterior
Gray's	subject #148 580
Supplies	cerebellum
Source	basilar artery
Vein	inferior cerebellar veins

The anterior inferior cerebellar artery passes backward to be distributed to the anterior part of the under surface of the cerebellum, anastomosing with the posterior inferior cerebellar branch of the vertebral. It supplies the anterior inferior quarter of the cerebellum.

Clinical significance

Occlusion of AICA results in lateral pontine syndrome, also known as AICA syndrome.
