(a) Contrast-enhanced computed tomography findings at the time of admission showing bile and pancreatic duct dilation and increased radiodensity around the pancreatic head. A pancreatic pseudocyst could also be observed (arrow). (b) Contrast-enhanced computed tomography after treatment for acute cholangitis and pancreatitis showing tumor (arrow) in the main pancreatic duct at the pancreatic head. The high-density structure in the bile duct was due to the endoscopic retrograde biliary drainage tube. Note the improvements in dilation of the bile and pancreatic ducts.

C-reactive protein, 25.14 mg/dL; carcinoembryonic antigen, 1.3 ng/mL; CA19-9, 16.1 U/mL; and SPAN-1, 16.2/mL. Contrast-enhanced CT findings at the time of admission showed bile and pancreatic duct dilation and increasing radiodensity around the pancreatic head (Fig. 1a). Contrast-enhanced CT performed after treatment of cholangitis and pancreatitis revealed a tumor detail at the pancreatic head (Fig. 1b).
Endoscopic retrograde cholangiopancreatography (a) and magnetic resonance cholangiopancreatography (b) showing stenosis of the common bile duct and main pancreatic duct.

ERCP and magnetic resonance cholangiopancreatography (MRCP) showed stenosis of the distal bile and main pancreatic ducts (Fig. 2a and b).
Histopathological findings revealed dilation of the pancreatic duct, and proliferation of columnar cells and cuboid epithelial cells occupying the main pancreatic duct of the pancreatic head. (a) low-power field, (b) high-power field.

Histopathological findings revealed dilation of the pancreatic duct, and proliferation of columnar cells and cuboid epithelial cells in the main pancreatic duct of the pancreatic head (Fig. 3).
