A 31-week gestation male infant with respiratory distress since day of delivery had lobectomy at 8 weeks of age for symptomatic, suspected congenital pulmonary airway malformation (CPAM). Histology of resected lung showed cytomegalovirus (CMV) inclusion bodies and emphysematous changes. The infant was treated with antiviral therapy with improvement in symptoms. CMV infection of the lung should be considered in any neonate presenting with lung cysts.
