Figure 1 A, Chest radiograph demonstrating multiple bilateral variable-sized pulmonary nodules, some of which show central cavitation (arrows). B-C, CT scan of the thorax showing multiple variable-sized, randomly distributed pulmonary nodules predominantly in the lower lobes. Many show central cavitation. There is no halo surrounding the nodules. CHEST 2014 145, 1419-1424DOI: (10.1378/chest.13-2081) Copyright © 2014 The American College of Chest Physicians Terms and Conditions
