Abstract

Introduction: Congenital Cystic Adenomatous Malformation (CCAM) is an infrequent entity due to an alteration in alveolar-pulmonary development. 

Material and Methods: A descriptive, retrospective study of newborns presenting CCAM in a tertiary care hospital in Madrid, Spain. 

Results: Seven patients were found. All were full term, normal weight births. Two patients showed respiratory distress at birth. Two chest x-rays were normal. CT scans showed three clear CCAM lesions, four suggestive of hybrid lesions. All were referred to medical centers with pediatric surgery for followup. 

Discussion: At birth, this pathology may be asymptomatic and appear as a chest x-ray finding. Long term management is complicated by infection and malignization. Conservative treatment of asymptomatic patients includes regular follow up of lesions. Surgical treatment is reserved for symptomatic or complicated patients. 

Conclusions: Prenatal suspicion of CCAM is important since clinical exam and radiology may be normal in neonatal period. Chest CT scans are important in confirming diagnosis and determining future surgery. More studies are necessary for the proper diagnosis and management of this disorder.
