중심부 석회화를 동반한 간내 담관암 1예

Abstract

중심부 석회화를 동반한 간내 담관암은 국외에서 1예 보고 되었을 정도로 매우 드문 증례이며, 담관내 석회화 소견을 보이는 환자의 감별진단에 있어서 간내 담도암에 대한 고려와 조직검사가 필요할 것으로 판단되어 중심부 석회화가 동반된 간내 담관암 증례를 보고하는 바이다. A 50-year-old woman complained of jaundice and dyspepsia that started 2 weeks prior to consultation. 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.
