Parent artery occlusion for peripheral anterior inferior cerebellar artery aneurysm. A case report and review of the literature.

Most cases of aneurysms associated with the distal portion of the anterior inferior cerebellar artery resulted in a hearing disturbance from the surgical procedure, although aneurysms far from the auditory artery had no deficit from trapping. We describe a patient with an aneurysm at the distal segment of the anterior inferior cerebellar artery (AICA) treated endovascularly by parent artery occlusion.
