摘　　要：目的 :分析早期肝脓肿在病变发展过程中的CT表现 ,提高早期肝脓肿的CT诊断水平。方法 :回顾性分析12例经手术病理及临床治疗证实的早期肝脓肿的CT表现 ,并与肝癌、肝转移瘤、肝血管瘤等进行比较。结果 :早期肝脓肿CT平扫为均匀或不均匀的低密度影 ,增强扫描CT表现因肝脓肿病变发展阶段不同而异 ,可出现斑片状强化、细网格征、蜂窝征、簇型征、持续强化征 ,病灶范围缩小。结论 :增强及延时CT扫描有助于提高对早期肝脓肿的诊断及鉴别诊断。Objective:To analyse the CT features of early pyogenic hepatic abscess during different stages of patho- logy and improve the accuracy of CT diagnosis.Methods:The CT appearances of 12 cases of hepatic abscess proved by surgery or other clinical methods were retrospectively analysed and compared with CT findings of cavernous hemangiomas or hepatocellular carcinoma or hepatic metastases.Results:Plain CT demonstrated nonspecific features of early pyogenic hepatic abscess such as homogenous or inhomogeneous lower density.The enhancement features of the abscess varied with different stages,displayed as ①patchy enhancement;②fine netwire sign;③honeycomb sign;④cluster sign;⑤prolonged enhancement with decrease of the extent.Conclusion:Enhanced CT scanning with delayed scanning of liver are very helpful to improve accuracy of the diagnosis and differential diagnosis of early pyogenic hepatic abscess.
