Figure 1 CT images (lung settings (A), mediastinal settings (B) acquired in a female patient with empyema necessitans (EN) and a persistent air leak related to a ruptured right lower lobe lung abscess. Extensive subcutaneous emphysema is highlighted in panel A (white asterix), which also shows right lower lobe lung consolidation (black arrow), an adjacent hydropneumothorax, a small left pneumothorax and a pneumomediastinum. Panel B shows a defect in the parietal pleura and subpleural tissues (white arrow), resulting in discharge of infected pleural fluid into the subcutaneous tissues (EN, white asterix).
