摘要
目的:探讨早期细菌性肝脓肿的CT平扫及增强扫描的特点,提高其CT诊断水平。材料和方法:回顾性分析16例经临床治疗、CT随访或穿刺病理证实为细菌性肝脓肿的CT平扫和增强扫描的影像表现。结果:早期细菌性肝脓肿CT平扫时表现为均匀或不均匀肝内低密度块影;增强扫描表现为病灶明显增强,且持续时间可达3～7min,其中,肿块缩小征12例,双环征5例,“簇状征”4例,“花瓣征”4例和一过性增强征3例。结论:CT增强扫描对早期细菌性肝脓肿有较高的诊断价值。
Purpose： To study plain and enhanced CT appearances of the early pyogenic hepatic abscess and improve the accuracy of CT diagnosis. Materials and Methods： The features of the piain and enhanced CT scanning were analyzed retrospectively in 16 cases with pyogenic hepatic abscess proved clinically through CT following up or biopsy. Results： Plain CT scanning appeared the lesions as a homogeneous or inhomogeneous hypodense mass, and enhanced CT scanning appeared them with obvious hyperdense enhancement and prolonged 3 - 7 minutes. Of them, there were ＂diminished mass sign＂ （ n = 12）, ＂doubling sign＂ （ n = 5 ）, ＂cluster sign＂ （ n = 4）, ＂rosette sign＂ （ n = 4） , ＂transient enhancement sign＂ （n = 3 ）. Conclusion： A enhanced CT scanning is very helpful in the diagnosing of early pyogenic hepatic abscess.
