[Congenital Pulmonary Airway Malformation Diagnosed in Adulthood].

Congenital pulmonary airway malformation diagnosed in adulthood is very rare. A 54-year-old woman was admitted to our hospital with complaints of abnormal chest shadow. Computed tomography( CT) demonstrated multiple cysts, mass lesions, and consolidation in left lower lobe. Bronchofiber scopy could not establish the diagnose. Left lower lobectomy was performed for diagnosis and treatment. Pathologically the lesion was diagnosed as congenital pulmonary airway malformation.
