Evaluation of lung bases is limited due to the presence of low lung volumes , but there is likely mild bibasilar atelectasis . It is difficult to exclude the presence of trace bilateral pleural effusions . No pneumothorax is identified .
    OUTPUT:
    
Low lung volumes with bibasilar atelectasis .
