摘　　要：目的通过观察分析肝脓肿CT平扫及动态增强扫描的表现及特征,提高肝脓肿诊断的准确性。方法回顾性分析经临床、手术及穿刺证实的26例肝脓肿病例的CT表现,着重观察并记录脓肿的部位、形态、数目及增强前后的CT表现,并结合临床资料进行分析。结果肝脓肿平扫表现为密度低于周围肝实质的病灶,部分病灶内可有气体增强扫描时的环靶征、有分隔并强化为典型肝脓肿的特征表现。不典型肝脓肿常表现为肿块缩小征、肝组织一过性异常灌注、蜂窝征或簇状征。结论 CT动态增强扫描可作为诊断肝脓肿的首选影像学方法。Objective To observe and analyze the performance and features of hepatic abscesses （HA） in plain and tripie- phase enhanced CT to improve the diagnostic accuracy. Methods A total of 26 cases with HA which were confirmed by clinical or pathologically were retrospectively analyzed. Mainly to observe and record the site, shape, number and enhanced CT performance,and then analyzed combining with clinical data. Results There appeared low density lesions in HA in pain scaning. In some cases there contained air in the cavity. Circular target sign and septal enhancement were special CT man- ifestations of hepatic abscess. Atypical hepatic abscess often presented as mass-narrow sign, transient hepatic parenchyma enhancement （THPE）, honeycomb sign or cluster sign. Conclusion Dynamic enhanced CT can be served as the principal method in diagnosing HA.
