    INPUT: Assessment of the chest is slightly limited by patient rotation . Cardiac silhouette size is mildly enlarged . Mediastinal and hilar contours are grossly unremarkable . Lungs are hyperinflated without focal consolidation . Minimal blunting of the costophrenic angles posteriorly on the lateral view could suggest pleural thickening or tiny bilateral pleural effusions . No pneumothorax is identified . There are mild multilevel degenerative changes seen within the thoracic spine .
    OUTPUT:
    
Lung hyperinflation suggestive of COPD . Blunting of the costophrenic angles posteriorly on the lateral view could suggest pleural thickening or trace bilateral pleural effusions .
