Aberrant right subclavian artery is the most common anomaly of the aortic arch. The frequency of such irregularity is about 0.5-1% of the population with this condition. Common carotid trunk is another anomaly of the aortic arch. The frequency of coexistence of the two conditions, aberrant right subclavian atery with common carotid trunk, is extremely low. We report such a case of coexistence.
