Figure 2 : Right lung X-ray from day 15, 16, 23, and 25, respectively. The patient presented with right lung pneumothorax and subcutaneous emphysema of the chest wall. The right lung volume was compressed above 90% (Figure a), and he urgently received closed thoracic drainage. Six hours later, the chest radiograph shows that the lung had mostly recovered (Figure b). On day 23, the patient presented with new right lung pneumothorax (Figure c), and on day 25, the chest radiograph shows that the lung had largely recovered (Figure d).
