Posterior-anterior and lateral chest radiographs should be obtained in all patients. Expected general findings include increased pulmonary markings, honeycombing, atelectasis, and pleural changes. Specific findings may include linear lucencies and parallel markings radiating from the hila (tram tracking) in cylindrical bronchiectasis, dilated bronchi in varicose bronchiectasis, and clustered cysts in cystic bronchiectasis. In the appropriate clinical setting, chest radiograph findings are occasionally sufficient for confirming the diagnosis of bronchiectasis.
