    INPUT: The heart size is normal . The aorta is diffusely calcified and tortuous . Hilar contours are normal . The lungs are hyperinflated with flattening of the diaphragms suggestive of underlying emphysema . Minimal blunting of the costophrenic angles on the posterior view may reflect tiny pleural effusions or pleural thickening . No focal consolidation or pneumothorax is seen . There is biapical pleural thickening and scarring . No pulmonary edema is present . There is diffuse demineralization of the osseous structures .
    OUTPUT:
    
Hyperinflated lungs suggesting underlying emphysema . Blunted costophrenic angles posteriorly may suggest tiny bilateral pleural effusions or pleural thickening . No radiographic evidence for pneumonia .
