    INPUT: The heart is mild to moderately enlarged . There is again a perihilar opacification , and a mild interstitial abnormality is present , worse in the right lung than left , but diffuse . Vascularity is also indistinct , suggestive of mild vascular congestion on this examination , similar to improved , but apparent differences may be largely due to technique . A focal right lower lung opacity , apparently in the right lower lobe , persists , worrisome for pneumonia without definite change . There is no pleural effusion or pneumothorax . Mild degenerative changes are present along the lower thoracic spine . In addition , there is an irregular appearance along the course of the right anterolateral fifth and possibly sixth ribs , suggestive of possible remote prior rib fractures .
    OUTPUT:
    
1 . Findings suggesting mild pulmonary vascular congestion . 2 . Focal right lower lung opacity , possibly pneumonia ( atelectasis could also be considered ) . Correlation with clinical symptoms is recommended and consideration of followup imaging is suggested if clinically indicated .
