Objective To investigate the contrast-enhanced ultrasound characteristics of hepatic focal inflammatory lesions (HFIL).Methods Fifty-five cases of HFIL underwent both preoperative conventional ultrasonography and contrast-enhanced ultrasound (CEUS) were enrolled in this study.Results Among the 55 patients,37 patients had a single nodule and 18 patients had multiple nodules.The mean size of the lesions was (3.8±2.2)cm.The lesions were divided into two groups (group 1:＜3 cm and group 2:≥3 cm) to evaluate the difference of the morphological and echoic heterogeneity and the difference was statistically significant (P＜0.05).There were three types of the lesions enhancement in our study:the overall enhanced(34.5 ％,19/55),the partially enhanced with partial unenhancement (38.2％,21/55) and the overall unenhanced(27.3％,15/55).Conclusions Contrast-enhanced ultrasound provides more information for the diagnosis of HFIL,which has a certain diagnostic value.%目的 探讨肝脏局灶性炎性病变(HFIL)的超声造影表现.方法 搜集本院行超声造影的55例HFIL,对比分析其常规超声及超声造影声像图特点.结果 55例患者中,单发37例,多发18例,病灶平均大小(3.8±2.2) cm,以3 cm为界值将病灶分为两组比较其常规超声特点,其中病灶形态规则性及回声均质性差异具有统计学意义(P＜0.05).其超声造影增强特点分为三种模式,整体增强型(34.5％,19/55)、部分增强型(38.2％,21/55)、完全不增强型(27.3％,15/55).结论 超声造影对HFIL的诊断可提供更多信息,具有一定诊断价值.
