Abdomen-pelvic computed tomography showed a 3 cm mass in the right hepatic duct with central calcification, which was spreading into the second branch. Repeated biopsies through endoscopic retrograde cholangiopancreatography were needed for pathology, which was consistent with an adenocarcinoma. Imaging studies including positron emission tomography showed no evidence of distant metastasis. The patient underwent right lobectomy with bile duct resection. The final diagnosis was intrahepatic cholangiocarcinoma with central calcification. We reported a very rare case of centrally calcified mass growing in the second branch of the right hepatic duct. The possibility of intrahepatic cholangiocarcinoma with central calcification should be considered for differential diagnosis of intrahepatic calcification.
