Its presentation or detection in adulthood is very rare. The aim of our study was to evaluate the clinical and radiological features of adult patients with this congenital malformation, as well as the management of this entity in older patients.Methods: Adult patients diagnosed with CCAM were evaluated for clinicoradiological presentation and management. 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: CCAM is rare in adults. Although adult patients may present with nonspecific thoracic symptoms, it is not unusual that this entity is incidentally diagnosed on routine chest imaging. Most adult CCAM of the lung can be safely treated with minimally invasive techniques, but conservative management is another reasonable option in certain clinical scenarios. %U
