Objective: To explore the clinical value of prenatal ultrasonography in diagnosis of fetal cystic lung diseases, especially congenital cystic adenomatoid malformation (CCAM) and pulmonary sequestration (PS). Methods: Totally 23 fetuses with suspected cystic lung disease underwent ultrasound examination. Serial ultrasonography was performed to monitor the development of the lesions and to assess the presence or absence of complications such as mediastinal shift, polyhydramnios, hydrops and other associated abnormalities. Then the outcome was evaluated during follow-up. Results: Twenty-three fetuses were diagnosed as congenital cystic lung diseases prenatally, including 20 CCAM (20/23, 86.96%), 2 PS (2/23, 8.70%) and 1 CCAM combined with PS (1/23, 4.35%). Mediastinal shift was found in 7 fetuses (7/23, 30.43%), polyhydramnios in 3 (3/23, 13.04%) and seroperitoneum in 1 (1/23, 4.35%). The follow-up outcome indicated that 9 fetuses were born alive (9/23, 39.13%), in 5 of which the lesions' volume reduced or even disappeared spontaneously before birth. And the pregnancy was terminated in other 14 fetuses (14/23, 60.87%). Conclusion: Prenatal ultrasonography is of great clinical value in diagnosis of fetal cystic lung diseases.
