Figure 2 (A) Abdominal ultrasound of the right upper quadrant, revealing echogenic material within the gallbladder lumen, compatible with hemobilia. (B) Ultrasound with colour Doppler demonstrating the “yin-yang” appearance typical for pseudoaneurysm. This figure is available in colour online at http://carjonline.org/.

Figure 3 (A) Hepatic angiogram, defining the hepatic vasculature with early filling of the pseudoaneurysm. (B) The cystic artery has been selectively catheterized confirming arterial flow to the pseudoaneurysm and early venous drainage (C). (D) The pseudoaneurysm has been coiled, with good occlusive effect. Canadian Association of Radiologists Journal 2012 63, 153-155DOI: (10.1016/j.carj.2010.07.005) Copyright © 2012 Terms and Conditions
