Corpus: Anterior inferior cerebellar artery

The anterior inferior cerebellar artery is a paired branch of the basilar artery and one of the three most important vessels supplying the cerebellum.

The anterior inferior cerebellar artery runs through the cerebellopontine angle. It supplies the medulla oblongata, the pons, the choroid plexus of the fourth ventricle and the anterior parts of the cerebellar hemispheres with arterial blood. In the internal acoustic pore, it can supply the labyrinthine artery.

Occlusion of the anterior inferior cerebellar artery leads to the so-called AICA stroke.
