目的 与病理结果对照，探讨产前超声诊断胎儿肺脏肿块的准确性。方法 回顾性分析产前超声诊断为胎儿肺脏肿块病例的超声声像图特征和合并异常，与引产后或出生后手术的病理结果进行比较。结果 123例经产前超声诊断为肺脏肿块并获得病理结果，其中18例引产，105例于出生后手术。10例产前无法确定肿块类别，其中5例病理为先天性肺囊腺瘤畸形（CCAM），5例为隔离肺(PS)。4例产前考虑CCAM，病理为先天性大叶性肺气肿。8例产前考虑为PS，病理为PS合并CCAM。1例产前考虑为PS，手术及病理为PS合并食道裂孔疝。产前超声完全符合率为81%。结论 产前超声可以检出胎儿肺脏肿块，与病理符合率较高。由于胎儿肺脏肿块超声表现的相似性，精确区分各类肿块有一定困难。
Objective To investigate the accuracy of prenatal ultrasound diagnosis of fetal lung masses when compared with pathologic findings. Method A retrospective analysis were done to demonstrate the characteristics of prenatal ultrasound diagnosis of fetal lung masses and concurrent anomalies，compared with the pathologic findings after termination of pregnancy or surgery after birth. Results The pathological results of 123 cases were obtained, in which 18 cases were terminated pregnancy, and 105 cases were performed surgery after birth. 10 cases were unsuccessfully determined the category of masses prenatally，in which 5 cases were identified as congenital cystic adenomatoid malformations (CCAM) and another 5 cases were pulmonary sequestrations (PS) by pathology.4 cases diagnosed with CCAM prenatally were identified as congenital lobar emphysema by pathology. In 8 cases considered as PS by prenatal ultrasound, the pathology proved to be PS with CCAM.1 case was diagnosed prenatally with PS, but the surgery and pathology confirmed to be PS with hiatal hernia. To sum up, prenatal ultrasound complete coincidence rate was 81%. Conclusions Prenatal ultrasound can detect fetal lung massed, and the coincidence rate with pathology is higher. While because the similarity of sonographic findings in fetal lung masses, it is difficult to accurately distinguish all kinds of mass.
