CT of the abdomen demonstrates a stent located within the common bile duct (CBD) and an elongated cystic structure located adjacent to the CBD proper. Surgical clips are seen at the distal end of this structure, from prior gallbladder removal. A small amount of non-dependent pneumobilia is present, as expected with the presence of a biliary stent. There is no intra- or extrahepatic biliary dilation; a small air-fluid level is seen within the CBD stent proximally.
