Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is normal in size . The mediastinal and hilar contours appear within normal limits . The lungs are hyperinflated . There is patchy scarring at each lung apex but no evidence for pneumothorax . There is no pleural effusion . The lateral view depicts a geographic peripheral opacity which correlates with poor delineation of the cardiac border along the medial left lung base . However , some of this appearance may correspond to a patchy opacity in the left lower lung seen more laterally that suggests a developing pneumonia .
    OUTPUT:
    
Findings suggest pneumonia in the left lower lung , although it is not clear that the entirety of peripheral geographic opacity seen on the lateral view obscuring the anterior left hemidiaphragm entirely reflects pneumonia as opposed to an epicardial fat pad . Management alternatives include a short - term followup after treatment or consideration of chest CT to delineate the findings further if needed clinically .
