肝内胆管细胞癌(PCC)是肝脏原发恶性肿瘤,仅次于肝细胞癌,它起源于二级胆管在内的末梢侧肝内小胆管,约占所有胆管细胞癌的10%,早期发现和诊断具有重要的临床意义。作者回顾分析本院1998至2004年间手术及病理证实的16例PCC的CT表现,探讨其CT特征及在与肝内其它病变鉴别的意义。1 Intrahepatic cholangiocarcinoma (PCC) is a primary malignant tumor of the liver, second only to hepatocellular carcinoma. It originates from the small bile duct in the distal side of the secondary bile duct, which accounts for about 10% of all cholangiocarcinomas. And the diagnosis has important clinical significance. The authors retrospectively analyzed the CT findings of 16 cases of PCC confirmed by surgery and pathology from 1998 to 2004 in our hospital and discussed their CT features and their significance in distinguishing other lesions in the liver. 1
