Abdominal computed tomography showed gallbladder stones, wall
thickening, and choledocholithiasis with slight dilatation of the
intrahepatic bile ducts (Figure 1A). Magnetic resonance
cholangiopancreatography (MRCP) revealed gallbladder stones with slight
dilatation of the intrahepatic bile ducts, and blurred lower common bile
duct (Figure 1B).
