Published:September 12, 2022DOI:https://doi.org/10.1016/j.amjms.2022.09.005
      A 60-year-old female patient was referred for consultation due to a neck mass. Doppler ultrasound revealed the presence of arterial flow and doppler signals at the suspected location and computed tomography (CT) scan confirmed the presence of a high-lying right brachiocephalic artery (RBCA) extending above the thoracic outlet (Fig 1, black arrow). The bifurcation of the brachiocephalic trunk was located cranially at the right sternoclavicular joint and caudally at the right thyroid lobe. No aneurysmal expansion, stenosis, or compression of the trachea or venous structures were identified. The branching pattern of the great arteries was normal (Fig 1, red and yellow arrows). The vascular surgeon recommended follow-up.
