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.
It also gives off the Labyrinthine artery in most cases, however it could also be a branch of the basilar artery in others.
Clinical significance
Occlusion of AICA results in lateral pontine syndrome, also known as AICA syndrome.
