Cystic adenomatoid malformation of the lung: Prenatal diagnosis, prognostic factors and fetal outcome

Aim: To evaluate 14 cases of cystic adenomatoid malformation (CAM) of the l ung with regard to antenatal management and fetal outcome. Results: Intraut erine shunts were placed in 3 fetuses to avoid pulmonary hypoplasia.-Prenat al sonography showed that the lesions had a tendency to resolve in 4 cases. Of the 9 infants who survived, 5 were treated surgically (lobectomy), Conc lusions: The antenatal evolution of these lesions is highly variable; the l esions may even resolve spontaneously, therefore the diagnosis of CAM types II and III should be followed by a period of observation. Intrauterine dra inage is recommended in cases of CAM type I if unfavorable prognostic facto rs are encountered.
