肝包虫病的螺旋CT表现及鉴别诊断

The Spiral CT Manifestations of Liver Echinococcosis and Its Differential Diagnosis

目的观察肝包虫病的螺旋CT表现,以便作出正确的CT诊断。方法 2003年1月-2010年1月,临床证实的35例肝包虫病患者行螺旋CT平扫及增强扫描,对其CT表现进行分析。结果多发病变30例,单发病变5例。囊性病变32例,其中囊壁钙化29例,囊壁内囊分离2例,囊内见子囊11例;实质性肿块3例,均见斑点状钙化。结论肝包虫病的螺旋CT表现有其特殊性,螺旋CT基本能作出正确的诊断。但有时需与肝脏其它疾病鉴别。

Objective To improve the understanding of liver echinococcosis and make correct diagnosis of the disease by analyzing its spiral CT characteristics.Methods From January 2003 to January 2010,35 patients with clinically confirmed liver echinococcosis underwent spiral CT simple scan and enhanced scan.The results of CT scan were analyzed.Results There were 30 cases of multiple lesions and five cases of single lesion.Cystic lesion occurred in 32 cases,including 29 cases of cystic wall calcification,two cases of separated endocyst from the cystic wall.Daughter cysts could be seen in 11 cases of cystic lesion.Substantial mass could be seen in therr cases with spotty calcification.Conclusion The spiral CT manifestation of liver echinococcosis has its particularity.Basically,it can make the correct diagnosis.However,the diagnostic results sometimes need to be distinguished from other liver diseases.
