Anterior inferior cerebellar artery (AICA) loops have been associated with audiological and facial symptoms due to vascular compression of the 7th and 8th cranial nerves.
Chavda classified vessels according to their anatomic location 1:
- type I: lying only in the CPA, but not entering the internal auditory canal (IAC)
- type II: entering, but not extending >50% of the length of the IAC
- type III: entering and extending >50% of the length of the IAC
