Radiographic findings of the pyloric gland adenoma of the cystic duct. Abdominal computed tomography revealed markedly dilated intrahepatic bile ducts (A, arrow), and a polypoid tumour in the common hepatic duct just below the bifurcation (B, arrow). Endoscopic retrograde cholangiopancreatography confirmed the polypoid mass lesion (C, arrow) and demonstrated consecutive dilation of the central intrahepatic bile ducts. Endosonography verified the polypoid intraluminal tumour of 2.1 x 1.1 cm in the common hepatic duct (D, arrow) next to the portal vein.
