Figure 1 Chest computed tomography showing multiple bilateral masses. Some masses bordered on the pleura and one of the masses developed around a bronchus (arrow).

Figure 2 The mass around the bronchi is on the pleura above the diaphragm (arrows).

Figure 3 Coronal plane chest computed tomography showing a cavity replaced by a solid mass which was connected to the bronchi in the right lower lobe.

Figure 4 Chest computed tomography showing the right pneumothorax. The cavity wall ruptured into the pleura (arrow).
