摘　　要：目的：研究肝脓肿的ＣＴ表现。方法：回顾分析了６７例手术或临床证实的肝脓肿病例的ＣＴ及临床资料。结果：肝脓肿的ＣＴ表现变异较大，大致可分为３种类型：①圆形或类圆形低密度区伴环状强化，脓肿壁外围可有低密度环呈“双靶征”，３６例；②多房或蜂窝状低密度区，病灶内房隔及细小脓肿壁均可强化，１８例；③形态不规则、分界不清、密度不均的低密度肿块伴不同程度的强化，１３例。部分病例可兼有后两类表现，即低密度肿块内可见多房分隔或多个小环状更低密度区。结论：ＣＴ检查能较准确地作出肝脓肿的诊断，应作为肝脓肿的首选检查方法。Objective: To investigate the CT features of hepatic abscess. Methods: CT film and clinical data of 67 cases of hepatic abscess were reviewed. Results: The CT features of hepatic abscess were variable and could be classified into 3 types: ① Round hypodense area with ring enhancement and a hypodense outer rim around the abscess membrane (double target sign) in 36 cases; ② Multiloculated or honeycomb like hypodense area with septa and lesion which could be enhanced in 18 cases; ③ Irregularly marginated and poorly defined hypodense mass with variable enhancement in 13 cases. Of all the 67 cases, some exhibited the features of the latter two types simultaneously. Conclusion: CT scanning can accurately diagnose hepatic abscess and thus it is of first choice in detecting hepatic abscess.
