血吸虫性肝硬化的CT表现

CT diagnosis of hepatic cirrhosis caused by schistosomiasis

目的 分析血吸虫性肝硬化的CT表现。方法 回顾分析 2 3例血吸虫性肝硬化的CT征象 ,包括肝脏形态、大小、轮廓、密度、钙化及合并症等。结果 2 3例中 2 1例肝脏变形 ,肝左叶增大 18例 ,几乎均有不同程度的钙化 ,其中线形钙化 13例 ,网格状钙化 10例 ,斑块状钙化 8例 ,门静脉及其属支钙化 8例 ,合并肝癌 6例 ,合并胆囊结石 4例。结论 肝内钙化和左叶增大为血吸虫性肝硬化的主要CT征象 ,慢性血吸虫病人的肝癌发生率显著高于非血吸虫病患者 ,当合并肝内占位时应注意与大型虫卵结节相鉴别。

Objective To analyse the CT manifestations of hepatic cirrhosis caused by schistosomiasis. Methods CT features in 23 cases of hepatic cirrhosis caused by schistosomiasis were analysed retrospectively, including the shape, size, edges, density, calcification and complication. Results Of 23 cases, shape changed in 21 cases, left lobe enlarged in 18 cases. Almost all accompanied with calcification, in which linear calcification in 13 cases, reticular calcification in 10 cases, intratumoral calcification in 8 cases, portal vein and its tributaries calcification in 8 cases, and 5 cases with hepatocellualar carcinoma, 4 cases with stones of gallbladder. Conclusion Calcification in liver and left lobe enlargement were the most important CT characteristics of hepatic cirrhosis caused by schistosomiasis. The incidence of hepatocellular carcinoma in patients with chronic hepatic schistosomiasis was significantly higher than that without schistosomaiasis. Nodule of large ova should be distinguished with the carcinoma when HCC is companied. [
