肝脓肿的CT诊断

目的分析不同病理演变时期肝脓肿的CT表现,提高对肝脓肿的诊断水平。方法回顾分析经临床病理证实的50例不同发病时期肝脓肿的CT平扫及三期强化特点,并与肝癌、肝转移瘤、肝血管瘤等对照分析。结果按照肝脓肿病变发展阶段不同,其CT表现可分3种。早期肝脓肿(10例,有2种表现形式:小房腔性和团块状肝脓肿),典型肝脓肿(38例)和纤维肉芽肿性肝脓肿(2例)。结论肝脓肿在不同病理演变时期CT平扫表现不同,动态三期强化扫描有助于提高肝脓肿诊断符合率。

CT Diagnosis of Hepatic Abscess

Objective To analyse the CT features of hepatic abscess in different stages of pathology so that to improve the accuracy of CT diagnosis.Methods The plain CT and triphase contrast-enhanced CT findings of hepatic abscesses in 50 cases proved by surgery or other clinical methods were retrospectively analysed and compared with CT findings of hepatic carcinoma,hepatic metastases and hepatic hemangiomas.Results CT features of hepatic abscesses were divided into three types according to different stages of pathology.Early pyogenic hepatic abscess(10 cases)had two types:small cavitation(9 cases)and mass(1 case).Typical pyogenic hepatic abscess(38 cases)and granulomatous hepatic abscess(2 cases).Conclusion CT findings of liver abscesses are different in different stage of pathologic changes,triphase contrast-enhanced CT is specific in diagnosing hepatic abscess.
