Abstract
Dual origin of the vertebral artery (VA) is an uncommon anatomical variation. We describe a case of duplication origin at right vertebral artery (RVA) found incidentally in one elderly patient on investigation for cerebral aneurysm. Angiogram study showed a pseudoaneurysm at V4 segment of the RVA associated with embryological anatomy. The authors performed a systematic review of the similar cases reported worldwide.
