    INPUT: Lung volumes are low . Heart size remains mildly enlarged , accentuated due to low lung volumes . The mediastinal and hilar contours are unchanged and within normal limits . Crowding of the bronchovascular structures likely relates to low lung volumes without overt pulmonary edema . Patchy opacities in lung bases most likely reflect atelectasis . No pleural effusion or pneumothorax is present . Clips project over the left axilla .
    OUTPUT:
    
Low lung volumes with mild bibasilar atelectasis .
