    INPUT: Postoperative changes in the right lung are redemonstrated , with loss of volume and tenting of the right hemidiaphragm . There are bilateral increased interstitial opacities compatible with interstitial edema . The right hilum is engorged and there is loss of the normal contour of the hilar bronchovascular bundles , compatible with hilar adenopathy and radiation changes better seen in recent PET - CT . A right middle lobe nodule seen on recent chest CT can not be properly assessed in this radiograph given superimposition of bony structures . No focal opacities are seen in the left lung . There is no pleural effusion or pneumothorax . Mild cardiomegaly .
    OUTPUT:
    
Interstitial pulmonary edema in the setting of mild cardiomegaly . Right hilar engorgement is compatible with hilar adenopathy and radiation changes better seen on recent PET - CT . A right middle lobe nodule seen on recent chest CT can not be properly assessed in this radiograph given superimposition of bony structures .
