Congenital bronchopulmonary malformations detectable on prenatal ultrasound include cystic adenomatoid malformation (CAM), lobar sequestration, and upper airway atresia. We describe three fetuses with prenatally detected intrathoracic lesions in which the associated pulmonary hyperechogenicity disappeared before delivery. In the first case of pulmonary sequestration, the infant was asymptomatic after birth. However, in a case of CAM and another with laryngeal atresia, respiratory distress developed after delivery, despite recent scans showing apparently normal lung fields. This experience suggests that ultrasonic resolution of hyperechogenic lung lesions in utero does not necessarily indicate resolution of the underlying pathology.
产前超声可检测到的先天性支气管肺发育畸形包括囊性腺瘤样畸形（CAM）、肺叶隔离症和上气道闭锁。我们描述了三例产前检测到胸腔内病变的胎儿，其相关的肺高回声在分娩前消失。在第一例肺隔离症病例中，婴儿出生后无症状。然而，在一例CAM和另一例喉闭锁病例中，尽管最近的扫描显示肺野明显正常，但分娩后仍出现了呼吸窘迫。这一经验表明，子宫内高回声性肺病变的超声消退并不一定表明潜在病理状况已消退。
