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

PURPOSE: Congenital cystic adenomatoid malformation (CCAM) of the lung in adults is very rare. We aimed to evaluate the clinicoradiological features of adult patients with CCAM.

METHODS: Adult patients diagnosed with CCAM were evaluated for clinicoradiological presentation and management.

METHODS: Nine 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.

CONCLUSIONS: CCAMs might be incidentally diagnosed on routine chest imaging in adults and can be safely treated with minimally invasive techniques.
