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 study CT manifestations of liver abscess. Methods: A retrospective analysis of 67 cases of surgically or clinically confirmed cases of liver abscess CT and clinical data. Results: CT findings of liver abscess varied widely and could be divided into three types: ① round or low-density circular areas with ring-like enhancement, abscess wall may have low-density ring was “double target sign”, 36 Cases; â ’multi-room or honeycomb-shaped low-density area, lesion within the septum and small abscess wall can be strengthened, 18 cases; â’ ¢ irregular shape, . In some cases, the latter two types of performance can be combined, that is, multiple compartments or multiple smaller lobed areas with lower density can be seen in the low-density mass. Conclusion: CT examination can make the diagnosis of liver abscess more accurately and should be the first choice of liver abscess.
