Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged including moderate cardiomegaly . Diffuse hazy opacification of each lung has worsened and is most suggestive of pulmonary edema . A focal component to opacification persists at the right lung base , but similar to the prior study ; differential considerations include pneumonia , atelectasis or a focal region of edema . There is no suggestion of substantial pleural effusion , although a small one would be difficult to exclude on the right .
    OUTPUT:
    
Worsening diffuse hazy opacification suggestive of pulmonary edema ; otherwise no significant change .
