成人期に診断された先天性肺気道奇形

Congenital Pulmonary Airway Malformation Diagnosed in Adulthood

先天性肺気道奇形（congenital pulmonary airway malformation：CPAM）は胎生期の気管支・細気管支の形成異常に伴い発生する疾患とされ1），成人期に診断されることはまれである．われわれは，成人期に診断しえたCPAMの1切除例を経験したので報告する．

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.
