Vertebral Artery Fenestration: A Rare Vascular Variation Case Report

Vertebral artery fenestration (VAF) is a rare congenital vascular anomaly that is discovered by incidental during imaging studies of patients who do not exhibit associated symptoms or who have intracerebral hemorrhage as a result of concurrent artery aneurysm or arteriovenous malformations. During catheter angiography, VAF may be mistakenly identified as dissection, hypoplasia, or stenosis. This case report describes a left VAF that was incidentally discovered during magnetic resonance angiography (MRA) utilizing the time-of-flight method.
