    INPUT: Lung volumes are slightly reduced . The heart size is top normal . The mediastinal and hilar contours are unremarkable . Mild interstitial prominence with peribronchial cuffing could suggest slight vascular congestion or airway inflammation . Patchy opacities in the lung bases may reflect atelectasis but are nonspecific , and aspiration is not excluded . No focal consolidation , pleural effusion or pneumothorax is seen .
    OUTPUT:
    
Mild interstitial prominence with peribronchial cuffing could suggest mild pulmonary vascular congestion or airway inflammation . Patchy bibasilar opacities are nonspecific , possibly atelectasis but aspiration is not excluded .
