Figure 1 Abdominopelvic computed tomography. Coronal contrast-enhanced abdominal computed tomography reveals a contracted gallbladder (white arrowhead) in close contact with the second portion of the duodenum (orange arrowhead), with a compromised fat plane between these two structures (white dotted line). A soft-tissue density (white arrow) connects the contracted gallbladder and transverse colon (asterisk).

Figure 2 Barium upper gastrointestinal series. The examination reveals a contrast-filling sac-like structure in the right lower quadrant of the abdomen (orange arrowhead) connected to the second portion of the duodenum (white arrowhead).
