Abstract
The right vertebral artery (VA) rarely arises from the right common carotid artery (CCA); however, the majority of anomalous right VAs are seen in combination with an aberrant right subclavian artery (SA). Independent (or isolated) right VA of the right CCA origin is extremely rare, with only a few cases reported previously. We herein report an additional case diagnosed incidentally using computed tomography angiography. This patient had a left VA arising from the aortic arch between the origins of the left CCA and left SA. The bilateral VAs took an anterior course and entered the C3 transverse foramina, at an extremely high level.
