    INPUT: Lung volumes are low . The cardiac , mediastinal and hilar contours are normal . Pulmonary vasculature is normal . There is minimal atelectasis in the lung bases . Minimal blunting of the costophrenic angles suggests trace pleural effusions bilaterally . No pneumothorax is seen . There are no acute osseous abnormalities . Known extensive sclerotic metastatic disease is better assessed on the previous CT .
    OUTPUT:
    
Low lung volumes with probable mild bibasilar atelectasis and trace bilateral pleural effusions .
