(a) A swelling in the right supraclavicular area. (b) Three-dimensional colored volume-rendered contrast-enhanced computed tomography shows a 30×25×28mm aneurysmal sac connected to the right thyrocervical trunk (R-ThcT). (c) The contrast-enhanced computed tomography shows the anatomical relationship between the thyrocervical trunk (ThcT) and the neck of the pseudoaneurysm. (d) Duplex ultrasound shows pseudoaneurysm totally thrombosed and no blood flow into the aneurysmal sac from the thyrocervical trunk. R-CCA, right common carotid artery; R-SA, right subclavian artery. Images in CAD 1
