While the associations between pulmonary sequestration (PS) and congenital diaphragmatic hernia (CDH) are known, CDH may be obscured by PS and thus, overlooked on prenatal ultrasonography when coexisting with PS. We present 2 cases of postnatally diagnosed CDH combined with PS. In both cases, PS was prenatally diagnosed as an isolated lung mass, while CDH was confirmed only after birth. Both newborns were sufficiently stable that management was not required immediately after birth. PS may function as an "anatomical barrier" to prevent herniation of the abdominal contents into the chest, thus acting as a "protector" providing normal lung maturation throughout pregnancy. If PS is suspected prenatally, coexisting CDH may be obscured; thus, close prenatal care and counseling of the parents regarding the possibility of CDH are essential. These infants should be delivered at a tertiary center, and imaging should be performed to exclude coexisting CDH.
虽然肺隔离症（PS）与先天性膈疝（CDH）之间的关联已为人所知，但CDH可能会被PS掩盖，因此，当与PS共存时，在产前超声检查中可能会被忽视。我们报告2例出生后诊断为CDH合并PS的病例。在这两个病例中，PS在产前被诊断为孤立性肺肿块，而CDH仅在出生后才得到证实。两个新生儿都足够稳定，出生后不需要立即进行处理。PS可能起到“解剖屏障”的作用，防止腹腔内容物疝入胸腔，从而在整个孕期作为“保护者”促进肺的正常成熟。如果产前怀疑有PS，可能会掩盖共存的CDH；因此，密切的产前护理以及就CDH的可能性对父母进行咨询至关重要。这些婴儿应在三级中心分娩，并应进行影像学检查以排除共存的CDH。
