Antenatal diagnosis of lung abnormalities by ultrasound has been a much more frequent occurrence in recent years. There is a range of appearances from uniform increased echogenicity through to lesions containing large echo-free areas. Bilateral uniformly increased echogenicity has a poor outlook but in all other situations outcome cannot be accurately predicted from an early second trimester scan. Follow-up through pregnancy often allows a fairly accurate prognosis to be made but the appearance of the lesion does not accurately predict histology. A conservative approach to the antenatal management of unilateral lesions is recommended with long-term postnatal follow-up for all lesions because of the unknown long-term outcome for the lesions, many of which are symptomatic postnatally.
近年来，通过超声进行产前肺部异常诊断的情况更为常见。其表现多样，从均匀的回声增强到含有大的无回声区的病变。双侧均匀回声增强预后不佳，但在所有其他情况下，孕中期早期扫描无法准确预测结局。孕期随访通常能做出较为准确的预后判断，但病变的外观并不能准确预测组织学情况。鉴于病变的长期结局未知，且许多病变在出生后会出现症状，对于单侧病变的产前管理建议采取保守方法，并对所有病变进行长期产后随访。
