    INPUT: The lungs are hyperinflated with flattening of the diaphragm suggesting chronic obstructive pulmonary disease . There is mild biapical pleural thickening . There is mild prominence of the interstitium diffusely which could in part relate to COPD ; however , raises concern for interstitial edema . No large pleural effusion is seen . The cardiac silhouette is mild - to - moderately enlarged . The aorta is calcified and quite tortuous . Right midhemithorax opacity may relate to mediastinal / vascular structures ; however , an underlying consolidation is difficult to exclude . There is diffuse osteopenia .
    OUTPUT:
    
1 . Enlarged cardiac silhouette and calcified and tortuous aorta . Medial right midhemithorax opacity may relate to overlapping prominent vascular structures ; however , underlying consolidation is not excluded . 2 . Interstitial pulmonary edema . 3 . COPD .
