Figure 1. In A, a chest X-ray, taken at admission, shows right-sided pneumothorax. Notice the total collapse of the lung (upper white arrowhead), diaphragmatic bullae (lower white arrowhead), and widened intercostal spaces. The black arrow shows the depressed right hemidiaphragm. In B, a detail of the right lower lobe reveals inflated bullae in the collapsed lung. In C, a chest X-ray, taken an hour after the first one (A) and immediately after chest tube drainage (white arrow) shows the normal position of the hemidiaphragm (black arrow).
