Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hyperinflated , suggestive of emphysema . An ill defined right infrahilar opacity abutting the right cardiac sillhouette without obscuring it is not seen in the lateral view . No other focal opacities are identified . Biapical pleuro - parenchymal scarring is present . Cardiomediastinal and hilar contours are unremarkable . There is no pleural effusion or pneumothorax . No rib fractures are seen .
    OUTPUT:
    
1 . Right infrahilar opacity is not clearly seen in the lateral view and may represent a focus of consolidation such as atelectasis / pneumonia versus summation of structures . Correlate clinically . 2 . No evidence of rib fractures . Of note , this study has suboptimal sensitivity for the detection of rib fractures and dedicated rib series or chest CT are more sensitive .
