Cystic adenomatoid malformation of the lung in adult patients: clinicoradiological features and management

PurposeCongenital cystic adenomatoid malformation (CCAM) of the lung in adults is very rare. We aimed to evaluate the clinicoradiological features of adult patients with CCAM.MethodsAdult patients diagnosed with CCAM were evaluated for clinicoradiological presentation and management.MethodsNine patients were diagnosed with CCAM (four were incidentally diagnosed on chest imaging). Most cases appeared on computed tomography as thin-walled multiseptated cystic lesions. Two patients had another concurrent pulmonary developmental anomaly. Five patients were surgically treated and three conservatively.ConclusionsCCAMs might be incidentally diagnosed on routine chest imaging in adults and can be safely treated with minimally invasive techniques.
