CT检查在囊性肝内胆管细胞癌与肝脓肿诊断中的作用分析

The role of CT examination in the diagnosis of cystic intrahepatic bile duct carcinoma and liver abscess

目的探讨CT检查在囊性肝内胆管细胞癌与肝脓肿诊断中的作用。方法根据62例患者的病理结果分为囊性肝内胆管细胞癌组和肝脓肿组各31例,记录分析两组患者的病灶、CT检测情况。结果囊性肝内胆管细胞癌组病灶边缘清的病灶数要显著高于肝脓肿组,相反病灶边缘不清要明显偏低(P<0.05);肝脓肿组的靶征、分隔状强化、边缘强化环形完整、肿块缩小征和病灶积气上明显高于囊性肝内胆管细胞癌组,但肝脓肿组在边缘强化环形不完整、向心性延迟强化和肝包膜回缩征上明显低于囊性肝内胆管细胞癌组(P<0.05)。结论 CT检查囊性肝内胆管细胞癌与肝脓肿都会出现灌注异常、低密度影,临床诊断中要注意CT各个征象。

Objective To evaluate the role of CT examination in the diagnosis of cystic cholangiocarcinoma and hepatic abscess. Method According to the pathological results,62 patients were divided into two groups,namely,the cystic cholangiocarcinoma group（ group A）（ n = 31） and the liver abscess group（ group B）（ n = 31）. The lesions and the CT examination results of both groups were then recorded and analyzed. Findings The number of lesions with clear edge of group A was higher than that of group B,and the number of lesions with unclear edge of group A was significantly lower that of group B（ P〈0. 05）. The rate of target sign,separate like strengthening,edge enhancement full annular,reduction of the tumor syndrome and lesion product gas of group B was significantly higher than that of group A. The rate of incomplete edge of the ring enhancement,centripetal delay intensive and hepatic capsular retraction sign of group B was significantly lower than that of group B（ P〈0. 05）. Conclusion In CT examination,cystic both intrahepatic cholangiocarcinoma and liver abscess may bear symptoms of abnormal infusion and low density. The image signs should be differentiated in the clinical diagnosis of intrahepatic cholangiocarcinoma and liver abscess.
