An aberrant right subclavian artery described by David Bayford, is rare and one of the aortic arch anomalies. It
gives usually incidental findings. We present the case of a 57-year-old woman who was admitted to a neurology outpatient clinic due to
a headache and no obvious pathology was detected during a physical examination. In consequence of the brain and chest CT angiography,
incidental anomalies of the aortic arch branches were found and asymptomatic aberrant right subclavian artery and bicarotid trunk was
diagnosed. The presence of this anomaly is becoming increasingly important in avoiding vascular injuries and cerebral complications in
patients undergoing endovascular intervention on the aorta aortic arch surgery, thyroidectomy, or cervicothoracic surgery. So, detailed
knowledge of variations of the subclavian artery and bicarotid trunk is paramount for radiologists and surgeons operating on the region
of the anterior neck.
