The First of Congenital Cystic Adenomatoid Lung Malformation in Iraq: A Radiologic and Pathologic Study
Background: Congenital cystic adenomatoid lung malformation is a very rare condition characterized by replacement of normal pulmonary tissue with cysts of variable size and distribution. The condition is usually unilateral. Very few cases of bilateral and congenital cystic adenomatoid malformation with good outcome after resections of the lesions have been reported, and most cases were stillborn or died early during life. Patients and methods: A forty-day male infant presented with progressive respiratory distress since the first week of life observed at the Children Teaching Hospital of Baghdad Medical City was studied. The literature was reviewed with aim of describing the early documentation of the condition in the literature. Results: Clinically, the infant had significant respiratory distress interfering with feeding and evidence of shift of the mediastinum to the right. Chest X ray showed increased translucency of left lung field and mediastinal shit to the right. CT-scan showed large air-filled cyst in the left lung and small air-filled cyst in the right lung. The child was treated successfully by left upper lobecomy. The gross examination of two gray pieces of lung tissue showed on cut section microcysts that were apparent grossly. Microscopical examination showed intercommunicating cysts lined by cuboidal epithelium with gland like appearance confirming the diagnosis of congenital cystic adenomatoid malformation of the lung. Conclusion: A very rare case of bilateral congenital cystic adenomatoid malformation of the lung is reported and the early documentation of the condition in the literature is described.
