血吸虫病肝纤维化的CT诊断

目的：研究比较血吸虫病肝纤维化和其它原因所致肝硬化的ＣＴ表现异同点。材料和方法：对照分析了５０例血吸虫病肝纤维化、３０例其它原因所致肝硬化及５０例正常肝扫描的ＣＴ增强前后扫描表现。结果：血吸虫病肝纤维化在ＣＴ上出现条纹状和网格状高密度影有相当高的比例可达７０％，另外还可在门脉和脾静脉处等部位见到钙化影，肝脏各叶大小变化及比值与其它原因所致肝硬化无显著性差异。结论：肝脏内出现条纹状和网状高密度影是血吸虫病肝纤维化较具特征的影像学表现，ＣＴ对此具有很高的检测价值。

CT Diagnosis of the Schistosomial Fibrosis

Purpose: To assess the difference between the schistosomial fibrosis and the cirrhosis from other causes by CT imaging. Materials and Methods: Fifty schistosomiasis patients, thirty cirrhosis patients and fifly no liver disease patients were examined with plain and enhanced CT. The CT imagings of the liver were compared. Results: Sensitivity in the detection of the striped and reticular high densities were 70% approximately for the schistosomial fibrosis, the manifestatione can not be seen in the cirrhosis patients and no liver disease patients. The changes of the size and ratio of the liver were unremarkable between the schistosomial fibrosis and cirrhosis. Conclusion: The striped and reticular high density shadows of the liver in the CT imaging is likely to be the characteristic changes for the diagnosis of schistosomiasis.
