title: Congenital cystic adenomatoid malformation of the lung with an esophageal cyst: report of a case.
abstract: The authors report the case of a 7-month-old girl found to have both congenital cystic adenomatoid malformation of the lung (CCAM) and esophageal cyst. She suffered repeated episodes of pneumonia and exhibited signs of respiratory distress on admission to our hospital. Chest radiography and magnetic resonance imaging (MRI) showed 2 different kinds of cystic lesions. Resection of the lower lobe of the right lung and excision of the posterior mediastinal cyst were performed. Histologic examination showed Stocker type I CCAM and esophageal cyst. Coexistence of both CCAM and esophageal cyst is extremely rare. The authors speculate that the pathologies of this case originated from a regional disturbance of common embryologic origin during 2 different phases of lung-bud foregut malformations.
