Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP upright portable view of the chest was obtained . Lungs are hyperinflated , with flattening of the diaphragms , suggesting chronic obstructive pulmonary disease . There is slight increase in opacity at the right lung base as compared to the prior study , raising concern for underlying consolidation and this could be better evaluated with addition of lateral view . There is sclerosis at the posterolateral right eighth rib , question of prior rib fracture . No pleural effusion or pneumothorax is seen . Cardiac and mediastinal silhouettes are unremarkable .
    OUTPUT:
    
Questionable increased density at the right lung base could be due to an early pneumonia , although lateral view would be helpful for further evaluation . Increased sclerosis at the posterolateral right eighth rib . Correlates to subacute to old rib fracture on subsequent CT .
