The initial frontal chest radiograph demonstrates multiple left-sided rib fractures and a left pneumothorax with mediastinal shift towards the right, indicative of tension pneumothorax. There is also extensive subcutaneous emphysema. An endotracheal tube is seen terminating 2-3 cm above the carina. A radiopaque catheter is projected over the left upper hemithorax, which may represent a catheter in the left pleural space.
