Diagnosis of bile duct metastasis from gastric cancer by endoscopic retrograde cholangiopancreatography combined with choledochoscopy: A case report

Figure 1 Imaging examinations. A: Contrast-enhanced computed tomography suggested thickening of the cystic duct walls, common hepatic duct, and proximal common bile duct; B: Magnetic resonance cholangiopancreatography suggested partial dilatation of intrahepatic bile duct as well as stenosis of common hepatic duct and common bile duct; C: Positron emission tomography/computed tomography suggested nodular-like foci of metabolic increased in the area of biliary tracts of the hepatic hilar region. Orange arrow: The stenosis of common bile duct.
