THAD)的临床意义.方法:搜集 56 例经病理证实的肝外胆管细胞癌患者，分析肝外胆管细胞癌及其所致 THAD 的影像 学特征 a 另外搜集 13 例肝内其他病变患者，分析其 THAD 的影像学特征。结果 CT 动态增强检查时，肝外胆管细胞癌 与其所致的 THAD强化不同步。肝内其他疾病所致 THAD.不仅在肝内显示不同形态的 THAD.而且可见肝实质内异 常强化病灶。结论肝外胆管细胞癌所致 THAD具有其特征性影像学表现.正确认识 THAD对于肝外胆管细胞癌的珍 断、鉴别诊断且预后评估都具有非常重要的意义。 E关键词】 体层摄影术 .X 线计算机; 过性肝密度差异 5肝外胆单管细胞癌 中图分类号 R735. 7 ;R814. 42 文献标识码 :A 文章编号 :1006-9011(2011)09-1366-04 The clini由1 signification of the study 00 transient hepatic parenchymal attenuation differenc国 caused by extrah叩atic cholan- 目。carcinoma AN Feng-xin.

China [Abstract] Objective:To Study th巳 clinical signiIicatìon of transient hepatic parenchymal differences CTHAD) caused by extrahepatic cholangiocarcinoma. Methods: Wc co l1ected 56 cases who wcre demonstrated extrahepatic cholangiocarcinoma by pathology and other 13 cascs with lesions in the livcr. We analysed the charactcrs of extrahepatic cholangiocarcinoma and THAD caused by tumor , as well as the THAD caused by lcsions in the liver. Results :In thc dynamic enhanced CT im- agìnges. extrahepatic cholflngiocarcinoma and its THAD were not synchronous. In the 13 cases with lcsions in rhe 1iver. wc found differenτTHAD 8S wcll flS the lesions. Conclusion: THAD caused by cxtrahepatic cholangiocarcinomas have dis rinctive radiological characters. This is sìgnificant for doctors to diagnose THAD correctly. and is important for the diago- sis and differenrial diagnosis of cxtrahepatic cholangìocarc?nomas as well a臼 the evaluation of patients prognosis [Key wordsTransient hepatic parenchymal differences; Extrahepatic cholangiocarcinoIna; CT!
