Objective To explore the clinical significance and diagnosis value of ultrasonography for fetal lung disease. Methods A total of 61 cases of fetal lung disease was diagnosed and the data were retrospectively analyzed. Results In the 61 fetus of lung disease, ⑴ there were 31 fetuses with congenital cystic adenomatoid adenomatoid malforamation (CCAM), the ultrasound found that there were mass in fetus lung , they were mixed echo or large cyst or more little cyst or a hyperechoic in the mass. Among them, there were 2 cases of type Ⅰ, 16 cases of type Ⅱ, and 13 cases of type Ⅲ; 21 cases were labored, who were CCAM-confirmed by pathology, 3 fetus masses were disappeared, 7 cases were CCAM-confirmed with magnetic resonance (MR) after birth. ⑵ There were 19 fetuses with pulmonary sequestration (PS), the sonography was slightly hyperechoic mass in the lung, including 7 cases of induced labor and confirmed by pathology as PS, and 4 cases of mass disappeared, 8 cases confirmed by MR or computed tomography (CT) after birth. ⑶ There were 6 cases of congenital diaphragmatic hernia, the abdomnial viscera was seen in the chest, 5 cases were induced labor, and 1 survived after operation. ⑷ There were 5 cases of pleural effusion (PE), 4 cases were induced labor and 1 case of PE disappeared.
