    INPUT: The heart size is normal . The hilar and mediastinal contours are within normal limits . The lungs are hyperinflated , demonstrating hyperlucency in the upper zones , compatible with COPD . There is no pneumothorax , focal consolidation , or pleural effusion . An equivocal soft tissue nodule adjacent to the cardiac apex may represnt the left nipple . Linear bibasilar opacities are most compatible with atelectasis . Tenodesis screws are seen within the left humeral head . The patient is post-cholecystectomy .
    OUTPUT:
    
1 . Hyperinflated lungs with upper zone hyperlucency , compatible with emphysema . No superimposed acute intrathoracic process seen . 2 .
