Synchronous gallbladder and pancreatic cancer associated with pancreaticobiliary maljunction

Figure 1 Ultrasound. A: Ultrasound showing thick-walled gallbladder and intraluminal mass (arrow); B: Ultrasound showing right intrahepatic bile duct dilation.

Figure 2 Computed tomography scan. A: Computed tomography (CT) scan showing asymmetrical wall thickening of gallbladder (arrow); B: CT scan showing right intrahepatic duct dilation and small cyst in right lobe.

Figure 3 Abnormal junction of pancreatic duct and common bile duct (arrowhead). Marked dilation of proximal common hepatic duct (arrow).

Figure 4 Adenocarcinoma of the gallbladder. A: Tumor invades the serosa (HE, × 20); B: Tumor is well differentiated (HE, × 100); C: Lymphovascular invasions; D: Perineural invasions by the tumor are observed (HE, × 100).
