目的：探讨胎儿先天性大叶性肺气肿(CLE)的产前超声声像特点及其临床结局。方法回顾性分析2011年1月至2014年5月10例出生后确诊为CLE患儿的产前超声声像特点，随访其临床结局。结果10例产前超声发现胸腔高回声肿块胎儿出生后确诊为CLE，其中7例发生在左上肺叶，5例内有多发囊性回声，9例曾有心脏受压移位，肿块内未探及主动脉来源供血。出生后CT及病理均诊断为CLE。结论产前超声可检出胸腔高回声肿块，发生在上肺叶的肿块并占据整个肺叶时应高度警惕CLE的可能。%Objective To investigate the prenatal ultrasonic characteristics and clinical outcomes of fetal congenital lobar emphysema (CLE). Methods A retrospective analysis was done to demonstrate the prenatal ultra-sonic characteristics of 10 children diagnosed as CLE after birth from January 2011 and May 2014. The clinical out-comes were followed up. Results Ten patients were diagnosed with CLE after birth, whose prenatal ultrasound mani-fest hyperechoic masses in the fetal chests, in which 7 cases occurred in the upper left lobe, 5 cases were found with multiple cystic echo in the masses, 9 cases were detected with compression and shift of the heart. No aortic blood ves-sel that supplied blood to the mass was found in all the cases. All the cases were diagnosed as CLE by CT and patholo-gy. Conclusion Prenatal ultrasound can detect thoracic hyperechoic mass, and the masses locate in the upper lobe and occupy the whole lobe should be more vigilantly suspected the possibility of CLE.
