    INPUT: PA and lateral chest radiograph demonstrates hyperinflated lungs compatible with emphysematous changes . A subtle streaky opacity in the right lower lobe is identified potentially pneumonia . The remainder of the lungs appear clear . The cardiomediastinal and hilar contours are unremarkable . Persistent blunting of the right costophrenic angle is slightly increased suggestive of a very small right sided pleural effusion . There is no pneumothorax . Osseous structures are without acute abnormality .
    OUTPUT:
    
1 . Subtle right lower lobe streaky opacity for which an infectious process is possible versus atelectasis or airway inflammation . 2 . Hyperinflated lungs and probable emphysematous changes .
