摘      要：This report describes a rare case of hilar cholangiocarcinoma with intratumoral calcification that mimicked hepatolithiasis. A 73-year-old man presented to a local hospital with a calcified lesion in the hepatic hilum. At first,hepatolithiasis was diagnosed,and he underwent endoscopic stone extraction via the transpapillary route. This treatment strategy failed due to biliary stricture. He was referred to our hospital,and further examination suggested the existence of cholangiocarcinoma. He underwent left hepatectomy with caudate lobectomy and extrahepatic bile duct resection. Pathological examination revealed hilar cholangiocarcinoma with intratumoral calcification,while no stones were found. To the best of our knowledge,only one case of calcified hilar cholangiocarcinoma has been previously reported in the literature. Here,we report a rare case of calcified hilar cholangiocarcinoma and reveal its clinicopathologic features.
