Enhanced computed tomography (CT) showed massive portal vein thrombosis (black arrows). Only the portal branch of segment 6 is patent (white arrow). The gallbladder was collapsed and pneumobilia was seen in the biliary tract (asterisk) (a, b).

The gallbladder was collapsed and pneumobilia was seen in the biliary tract (Figure 1).
Doppler ultrasonography (US) showed a dilated duct-like structure without any flow in the umbilical portion of the liver (a). Blood flow was detected only in the portal branch of segment 6 (b).

Blood flow was detected only in the portal branch of segment 6 of the liver (Figure 2).
Magnetic resonance imaging (MRI) showed a fistula between the gallbladder and the colon (white arrow). A gallstone in the gallbladder was seen (yellow arrow), but no other gallstone was seen in the common bile duct by cholangiopancreatography (MRCP).

A gallstone in the common bile duct was not seen by cholangiopancreatography (MRCP) (Figure 3).
Intraoperative picture indicates that the transverse colon is tightly adherent to the fundus of the gallbladder (white arrow).
