Posterior inferior cerebellar artery aneurysm associated with arteriovenous malformation fed by the same artery.
A 37-year-old man presented with a peripheral aneurysm of the left posterior inferior cerebellar artery associated with a more peripheral arteriovenous malformation fed by the same artery. Recurrent subarachnoid hemorrhage occurred from rupture of the aneurysm. Review of the pertinent literature indicates that the aneurysm of the posterior inferior cerebellar artery originates from the peripheral portion of the artery, when associated with arteriovenous malformation.
