Abstract

Anomalous origin of vertebral arteries is a rare vascular anomaly and mostly discovered as incidental findings during computed tomography angiogram , magnetic resonance angiography or digital subtracted angiogram of the aortic arch and cerebral vessels. Herein, we present an extremely rare case of a 31-year-old female who presented with headache after emotional trauma. A conventional cerebral angiogram showed anomalous origin of the right vertebral artery. This finding was incidentally discovered, and it is of utmost importance for future head and neck endovascular interventions to avoid inadvertent arterial injury.
