腹部包虫病的CT诊断（附43例分析）

目的分析腹部包虫病的CT表现。方法回顾分析43例腹部包虫病，21例手术病理证实，另22例Casoni试验阳性并经CT及B超确诊。观察内容病灶部位、数目、大小、形态、密度、结构及边缘等。结果41例囊型包虫病分为单纯型7例，内囊分离型5例，多子囊型17例，实质钙化型8例，混合型4例。多数囊肿外壁与肝实质间有一细线样低密度（文献未曾提到过的表现），2例为泡型包虫病，呈不规则实质肿块。7例为腹内多器官、多部位包虫病。结论CT能够对腹部包虫病定性和定位。血道播散是腹部多器官、多部位、广泛分布包虫病的另一主要发病途径。

CT Diagnosis of Abdominal Hydatidosis

Objective:To analyse the CT features of abdominal hydatidosis and explore ther pathogenic pathways.Methods:The location,numbers,size,shape,density,structure and edges of focuses of 43 patients with abdominal hydatidosis were analysed.All of cases were diagnosed by CT ultrasound casoni skin test and pathologic biopsy.Results:41 cases with abdominal cystic hydatid were divided into five subtypes,other 2 cases were avleolar hydatids which menifested as irregular mixed-density masses.7 of all cases had been found focuses in nulti-organs in the abdomen.There was a fine-linear region of lower density between external membrane and liver tissue in the majority of hydatid cysts.Conclusion:CT can demonstrate the site and nature of abdominal hydatidosis.And the blood trasmission is one of main pathogenic paths of patients with multi-organs hydatidosis in the abdomen.
