Contrast-enhanced CT showing a HAP with an ABF, hemobilia, and upper GI bleeding. a-b Axial and coronal sections processed with a maximum intensity projection (MIP) of a contrast-enhanced CT, showing a pseudoaneurysm (thick black arrow) from the liver graft hepatic artery (thin white arrow). Immediately adjacent is the bile duct filled with iodinated contrast (black triangle), indicating the presence of an ABF with hemobilia. c-d Axial section of a contrast-enhanced CT showing contrast extravasation into the duodenum (Du), which increases in quantity between the arterial phase (c) and the venous phase (d), consistent with an upper GI bleeding (white head arrow)
