Outcome of congenital cystic adenomatoid malformation of the lung after antenatal diagnosis

We evaluated the outcome of fetuses diagnosed with having congenital cystic adenomatoid malformation (CCAM) on ultrasonographic examination and managed conservatively. A retrospective study of 19 cases of CCAM diagnosed antenatally in our hospital was conducted between 1990 and 2001. Complete clinical information was available for all patients, with a mean follow-up of 62 months. The median gestational age at which CCAM was diagnosed was 23 weeks and there were eight live births. With conservative postnatal management, seven neonates had no major complications and one developed bronchopneumonia. Taken together, the findings of the present study and a review of the literature strongly support the conservative management of selected neonates with CCAM.
