Fig. 1From: Gastric cancer simultaneously complicated with extrahepatic bile duct metastasis and portal vein tumor thrombus: a case reportImaging and endoscopic findings. a Abdominal computed tomography (CT) scan showed wall thickening of the lower bile duct (arrow). b Proximal side of the thickened bile duct was dilated (yellow arrow), and low density area in the portal vein on contrast-enhanced CT scan was considered a tumor thrombus (red arrow). c A defect in the lower bile duct (arrow) and dilatation of the upper side were revealed on magnetic resonance cholangiopancreatography. d Cholangiography showed the same findings as magnetic resonance cholangiopancreatography. The arrow indicated a defect in the lower bile duct. e Gastroduodenoscopy showed a type 3 tumor at the lesser curvature of the gastric antrumBack to article page
