肝脓肿CT诊断及鉴别诊断的探讨

Study the Diagnosis and the Differential Diagnosis of Hepatic Abscess

目的:探讨肝脓肿的CT征象及其特征性表现,提高肝脓肿诊断的正确率。材料与方法:回顾性分析经手术或临床证实的细菌性肝脓肿32例的CT表现;所收集病例均行CT平扫和动态增强扫描。结果:32例CT平扫病灶均表现为低密度,增强扫描脓肿壁表现为双环强化征18例,三环强化征3例,表现为分隔强化8例;表现边缘强化征19例。结论:CT扫描尤其是动态增强扫描对肝脓肿具有较高的诊断价值,CT扫描能准确显示肝脓肿的部位,且其CT表现具有一定的特征性,结合临床有助于肝脓肿的诊断和鉴别诊断。

Purpose： To evaluate CT features and CT findings of hepatic abscess and its pathologic basis. Materials and Methods： CT findings of hepatic abscess in 32 cases confirmed by surgery or clinical treatments were retrospectively ana- lyzed. Results ： Of the 32 cases, CT manifestations of hepatic abscess included signs of low density area, The enhancement of abscess cavitary walls show double rim （18cases） , three rim （3cases） and the multi -loculation or compart enhancement （Seases） , peripheral enhancement（19cases）. Conclusion： The CT manifestations of hepatic abscess were characteristic, CT especially dynastic contrast CT was helpful in the diagnosis of hepatic abscess, These manifestations were helpful in early diagnosing hepatic abscess not only in location but also in nature and etiology, CT provide the imaging gist to establish the treatment project as soon as possible.
