Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a new asymmetric perihilar opacification of the right mid lung . This is superimposed on moderate bilateral pleural effusions , similar to increased on the right and perhaps somewhat decreased on the left . Increased opacification at the right lung base may also reflect increasing atelectasis associated with a pleural effusion , although an area of infection is not excluded . Pulmonary vessels show upper zone redistribution and Kerley lines are present suggesting coinciding mild congestive heart failure but generally similar in extent .
    OUTPUT:
    
New large area of focal right perihilar opacification , superimposed on pleural effusions as well as findings associated with mild pulmonary edema . The asymmetry suggests superimposed pneumonia as the etiology , or perhaps aspiration in the appropriate clinical setting ; alternatively asymmetric pulmonary edema could be considered . Short - term follow - up radiographs may be helpful to reassess .
