【摘要】 目的:探讨肝脓肿的CT表现,特别是动态增强CT表现。方法:回顾性分析51例经临床或病理证实的肝脓肿病例的CT表现及临床资料,所有病例均行CT平扫,47例行增强扫描,其中35例行双期或三期(动脉期、门静脉期、延迟期)动态增强扫描。结果:62个肝脓肿中,典型肝脓肿23个,不典型肝脓肿39个,CT平扫均表现为较正常肝组织为低的低密度灶,部分病灶可见脓腔内气体。增强扫描可见:(1)环靶征;(2)一过性肝段性强化;(3)“簇集征”;(4)“分房征”;(5)病灶缩小征。结论:肝脓肿动态增强扫描的CT表现有一定特征性,充分反映了肝脓肿的病理变化,对肝脓肿早期诊断及鉴别诊断有重要价值。更多还原

【Abstract】 Objective:To study the CT features of hepatic abscesses, with emphasis on the dynamic enhanced CT.Methods:51 cases of hepatic abscesses, proved by clinical or pathological data were retrospectively analyzed. All of them were examined by plain CT scan, 47 cases were examined by enhanced scan. Among them, 35 cases were examined by enhanced double-phase or three-phase (arterial and portal venous and delayed phase) .Results:Of the 62 lesions, 23 lesions were typical and 39 lesions were atypical. In plain CT scan, the abscesses usually exhibited as hypodense mass and air can be seen in the cavity. On enhanced CT scan, the following signs should be noticed: (1) double target sign; (2) transient hepatic segmental enhancement; (3) cluster sign; (4) multiloculated sign; (5) mass diminution sign. Conclusion:The dynamic enhanced CT that fully reflects the pathological changes of hepatic abscesses is characteristic, so it is very important to early diagnosis and differential diagnosis.更多还原
