Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable AP chest radiograph was provided . Compared to the prior radiograph , there has been development of bilateral parenchymal opacities , worse on the right , with congestion of the central vasculature as well as the appearance of some Kerley B lines on the right . There is a moderate right pleural effusion and possibly small left pleural effusion . These findings suggest that the etiology is most likely asymmetric pulmonary edema , worse on the right . However , underlying infection , particularly in the right upper and lower lobe can not be excluded .
    OUTPUT:
    
1 . Findings most compatible with moderate asymmetric pulmonary edema , worse on the right ; however , underlying infection is difficult to exclude , particularly in the right upper and right lower lung . 2 . Bilateral pleural effusions , larger on the right .
