    INPUT: Portable upright AP chest radiograph shows pneumothorax at the right lung base where a thoracic catheter is seen just above this , unchanged in position compared to a film from several hours earlier . Increased haziness over the region suggests some fluid filling in this area . Surgical clips are seen at the right apex and despite the pneumothorax , there is volume loss on the right with mediastinal shift rightward . Subcutaneous emphysema at the base of the neck persists , but axillary air on the left appears decreased . The left lung is clear .
    OUTPUT:
    
No increase in size of right basilar pneumothorax with stable chest tube positioning . There may be some fluid filling in the pleural space .
