目的 分析手术病理证实的肝内胆管细胞癌的CT表现 ,并与病理进行对照 ,以期找到肝内胆管细胞癌的CT特征。方法 5例病人均应用德国西门子SOMATOMPLUSCT机做了CT平扫 ,4例做了CT动态增强扫描并做了延迟 3min及 7～ 9min的扫描 ,最后与病理进行了对照分析。结果 病灶增强表现为三个方面 :一为无强化区 ;二为强化逐渐增强区 ;三为延迟强化区。并且一个病灶可以同时见到此三种强化表现中的二种或三种。结论 肝内胆管细胞癌分区强化的特点及三种不同的强化表现 ,尤其是强化逐渐增强和延迟强化的特点是有特征意义的。
Objective To analyze the CT findings of intrahepatic cholangiocarcinoma confirmed by pathology and compare it with pathology in order to find the CT features of intrahepatic cholangiocarcinoma. Methods 5 cases of patients were all treated with a CT scan with a German Siemens SOMATOM PLUS CT machine. In 4 cases, CT dynamic contrast-enhanced scans were performed and 3 min and 7–9 min delays were performed. Finally, a contrast analysis was performed with the pathology. Results There were three aspects of lesion enhancement: one was non-enhanced zone; the other was enhanced gradual enhancement zone; and three was delayed enhancement zone. And one lesion can simultaneously see two or three of these three enhancements. Conclusion The characteristics of zonal enhancement of intrahepatic cholangiocarcinoma and three different enhancement manifestations, especially the characteristics of gradual enhancement and delayed enhancement, are characteristic.
