anterior inferior cerebellar artery

A branch of the basilar artery; it runs dorsally along the posterior edge of the pons and supplies blood to the hindbrain, the superior and middle cerebellar peduncles, and portions of the ventral cerebellum.

The three-dimension road map was acquired by conducting a 3-dimensional rotating angiography (3D-RA), which clearly revealed a right cerebellar bAVM of 3.1 cm x 3.2 cm x 2.2 cm in size with the feeders from the branches of the right superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA), and posterior inferior cerebellar artery (PICA).
