    INPUT: Widespread interstitial and airway abnormalities suggests the possibility of chronic lung disease , difficult to assess in the absence of older radiographs . Superimposed on this process is pulmonary vascular congestion and mild interstitial edema . Additionally , more focal opacities are present in the right upper lobe adjacent to the minor fissure and in the right middle lobe , partially obscuring the right heart border . Cardiac silhouette is moderately enlarged , and note is made of tortuosity of the thoracic aorta .
    OUTPUT:
    
Congestive heart failure with interstitial edema superimposed on likely chronic interstitial lung airways disease . Superimposed pneumonia in the right upper and right middle lobes are not excluded .
