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

at the right sternoclavicular joint and caudally at the right thyroid lobe. No aneurysmal
