    INPUT: Cardiac silhouette size is moderately enlarged , as seen previously . The aorta remains tortuous and diffusely calcified . Enlargement of the hila bilaterally suggests pulmonary arterial hypertension . Lungs are hyperinflated with emphysematous changes re - demonstrated . Mild pulmonary edema is present along with small bilateral pleural effusions . Patchy opacities within the lung bases may reflect atelectasis , though infection in the right lung base can not be completely excluded . No pneumothorax is identified . The osseous structures are diffusely demineralized with multilevel mild to moderate degenerative changes .
    OUTPUT:
