[Congenitial Pulmonary Airway Malformation in an Adult with Pneumonia].

Congenitial pulmonary airway malformation (CPAM) most commonly present respiratory distress in the prenatal or neonatal period, but may rarely be asymptomatic and is incidentally found in adult patients with acute or recurrent pneumonia. Herein, we report a case of a 26-year-old asymptomatic adult male patient with pneumonia of the right lower lobe. He was also found to have multiple cystic lesions in the same lobe which was suspected to be CPAM, and the right lower lobectomy was performed.
