A doctor has provided 1 answer
AICA: A prominent aica is a variant of normal anatomy. The aica is the anterior inferior cerebellar artery. It can be found within the canal called the iac or internal auditory canal, which is where the facial nerve (7th) and the cochlear vestibular nerves (8th) extend from the ear to the brain. If the aica is prominent, it is large and can compress and result in tinnitus, vertigo & even hearing loss.
