    INPUT: A newly placed OG tube terminates in the stomach . An endotracheal tube terminates in the mid to lower trachea . A right pigtail catheter remains in place . A geographic right lung perihilar airspace opacity is unchanged . A left basilar retrocardiac airspace opacity has slightly improved . There is no pneumothorax . There is stable moderate S - shape scoliosis of the thoracic lumbar spine . Small sternotomy wires are intact and aligned .
    OUTPUT:
    
No significant interval change in the right perihilar consolidation , which may be due to a combination of pulmonary contusion and right upper lobe atelectasis . A left basilar retrocardiac opacity has slightly improved , possibly due to resolving contusion , aspiration , or atelectasis .
