超声造影在不典型肝脓肿鉴别诊断中的意义

The significance of contrast-enhanced ultrasound in the differential diagnosis of atypical liver abscess

目的:探讨不典型肝脓肿超声造影的增强模式,评价超声造影在肝脓肿定性诊断中的价值。方法:回顾性分析和总结33例经确诊的不典型肝脓肿超声造影的增强特征,并联合增强CT进行分析。结果:不典型肝脓肿超声造影可表现为"花瓣征"、"蜂窝征"、肝段一过性增强,病灶造影后测值可增大、减小或基本不变;超声造影及增强CT对不典型肝脓肿的敏感性、特异性及准确性差异均无明显统计学意义(P>0.05)。结论:超声造影对不典型肝脓肿有较高的诊断价值,与增强CT联合应用可提高诊断率。

Objective： To investigate the enhancement mode and to evaluate the qualitative diagnosis of contrast-enhanced ultrasound of atypical liver abscess. Methods： The contrast-enhanced ultrasound features of 33 cases of atypical liver abscesses were compared with contrast-enhanced CT retrospectively. Results： The ＂Rosette sign＂, ＂Honeycombing sign＂ and transient enhancement sign were found in atypical liver abscesses. The measurements of lesions could increase, diminish, or basically remain unchanged. The sensitivity, specificity and diagnosis accuracy of atypical liver abscesses were not statistically different between contrast-enhanced ultrasound and contrast-enhanced CT（P0.05）. Conclusion： Contrast-enhanced ultrasound has higher value in the diagnosis of atypical liver abscesses, and combination with enhanced CT can improve the diagnostic accuracy significantly.
