A right-sided aortic arch (RA) with an abnormal origin of the left vertebral artery (VA) from the left common carotid artery (CCA) is extremely rare. RA with left VA-CCA has an interesting embryologic mechanism based on which transverse foramen (TF) of the cervical vertebra the VA entered into. A 55-year-old asymptomatic man was referred to us with a diagnosis of RA. Computed tomography showed RA with the aberrant left subclavian artery (SCA) arising from Kommerell diverticulum and the left VA originating from the left CCA (A). The supra-aortic vessels arose in the following order: left CCA, right CCA, right SCA, and aberrant left SCA (B). The right VA entered the C6 TF. The left VA entered the C5 TF (C). He had been observed because the size of his Kommerell diverticulum was 26 mm. The patient gave consent to publish his data and images.
