title: CT appearance of cystic adenomatoid malformations.
abstract: Four pediatric patients with cystic adenomatoid malformation (CAM) are reported to illustrate the CT appearances of this lesion. Two patients presented in infancy with respiratory distress and two in later childhood with superimposed infection. Multilocular cystic masses with thin walls were seen by CT in the neonate and small infants with uninfected CAM, while infected CAM appeared as a complex lesion on CT, with an admixture of solid and cystic tissue and with variable definition of margins.
