Prenatal diagnosis and management of congenital cystic adenomatoid malformation.
Congenital cystic adenomatoid malformation (CCAM) is a rare pulmonary malformation resulting from excessive overgrowth of the terminal bronchioles. We present two CCAM case studies: type I (macrocystic) and type III (microcystic), diagnosed by antenatal ultrasonography at 31 and 21 weeks' gestation, respectively. In the former, multiple dilated cystic masses in the fetal left lung, with polyhydramnios, were identified during the antepartum examination. A postnatal thoracotomy with lobectomy was performed due to persistent cyanosis and resulted in a good outcome. In the latter case, an echogenic mass with multiple cysts in the fetal right lung was detected by prenatal sonography. The parents decided to terminate the pregnancy after prenatal counseling.
