Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is elevation of the right hemidiaphragm . Overall , the lungs are otherwise hyperinflated . On the lateral view , there may be subtle increase in density in the posterior lung base which may be due to overlying structures although a consolidation is not excluded . Left basilar linear opacities suggest atelectasis / scarring . No pleural effusion or pneumothorax is seen . The cardiac silhouette is top - normal to mildly enlarged . There may be subtle callus formation at the lateral left seventh and ninth ribs which could be due to underlying subacute fractures .
    OUTPUT:
    
Elevation of the right hemidiaphragm . Questionable opacity projecting over the posterior lower lung on the lateral view , not well substantiated on the frontal view , which may project over the left lung base , consolidation not excluded . Subtle callus formation at the lateral left seventh and ninth ribs which could be due to underlying subacute fractures ; not optimally evaluated on this study . Correlate with patient history for acuity and consider additional imaging as clinically warranted .
