ABSTRACT In clinical practice, rare structural vascular variations pose important risks for clinical procedures such as diagnostic vascular interventions or surgical treatment. The authors herein describe a rare case of an unusual origin of both vertebral arteries in a singular adult male cadaver. The two right vertebral arteries independently originated from the right subclavian artery, while the left vertebral artery took origin from the aortic arch. The left vertebral artery entered the 5th transverse foramen while the two right vertebral arteries entered the 4th and 6th transverse foramen, respectively.
