Abstract 【Objective】To explore the prenatal ultrasound characteristics of Congenital Cystic Adenomatoid Malformation (CCAM) in the fetus and its influence on the prognosis of the fetus. 【Methods】A retrospective analysis was conducted on 52 fetuses with CCAM who underwent prenatal ultrasound examinations in our hospital from January 2021 to December 2023. The classification of CCAM, ultrasound characteristics, occurrence of complications and prognosis were evaluated. 【Results】Among the 52 cases of CCAM, there were 10 cases of large cystic type (type Ⅰ), 24 cases of medium cystic type (type Ⅱ), and 18 cases of microcystic type (type Ⅲ). Prenatal ultrasound features: Lesions were located on one side in 48 cases and on both sides in 4 cases. The volume ratio of type Ⅰ to type Ⅲ CCAM showed an increasing trend (P<0.05), and the ratio of lung volume to thoracic volume showed a decreasing trend (P<0.05). There was a statistically significant difference in the occurrence of polyhydramnios and fetal edema and effusion among different types of CCAM (P<0.05). The induction rate of labor in type Ⅰ - Ⅲ CCAM gradually increased. The comparison of the induction rates of labor in different subtypes of CCAM showed statistically significant differences (P<0.05).The follow-up of CCAM fetuses revealed that there was no statistically significant difference in the proportion of lesion volume reduction among different subtypes (P>0.05). The proportion of pulmonary consolidation and the proportion of those with respiratory symptoms in type Ⅰ- Ⅲ CCAM increased successively (P<0.05). 【Conclusion】Prenatal ultrasound is an effective tool for differentiating fetal CCAM and is of great value in predicting disease prognosis and improving the clinical outcome of neonates.
