Portal biliopathy refers to the changes in the bile duct caused by portal vein thrombosis or obstruction. It is assumed to be caused by cavernous transformation due to the development of the venous system surrounding the bile duct, but the exact pathology is still unknown. Biliary morphologic abnormalities of portal biliopathy are discovered incidentally on radiographic images, but it is sometimes difficult to differentiate them from cholangiocarcinoma. Given the poor prognosis of cholangiocarcinoma, a surgical approach can be considered when the diagnosis is uncertain. Herein, we report a case of portal biliopathy with bile ductal wall thickening, which was diagnosed after surgical resection was performed due to the presumed diagnosis of cholangiocarcinoma.
