4. The frontal chest radiograph shows pneumomediastinum
Frontal chest radiography shows bilateral perihilar ground-glass opacity, extensive subcutaneous emphysema, and pneumomediastinum- the latter is evidenced by the lucency around the heart due to “lifting” of the mediastinal pleura. This appearance should not be confused with pneumopericardium. An oval lucency involving the mid-thoracic trachea, surrounding the endotracheal tube, which is approaching the right mainstem bronchus is present. No focal consolidation or pneumothorax is seen. An endotracheal tube is present, approaching the right mainstem bronchial orifice, but no central venous catheter is present. No pleural effusion, either freely layering or loculated, is present.
