Congenital cystic adenomatoid malformation of the lung

The etiology of CCAM of the lung remains unclear. Presentations vary, with clinical outcomes that may be unpredictable. The neonatal nurse should be equipped to detect the sometimes subtle radiologic images these lesions produce and should be able to distinguish CCAM from similar chest masses. Expediting this diagnosis postnatally benefits the neonate by preventing further expansion of the cysts, which can cause a cascade of complications, including air leaks, cardiorespiratory compromise, and PPHN.
