    INPUT: Heart is normal size . Cardiomediastinal silhouette is stable . There is interval development of mild pulmonary interstitial edema and moderate bilateral pleural effusions , right greater than left . Increased opacification at the right base could represent asymmetric edema ; however , pneumonia will have a similar appearance . There is no pneumothorax .
    OUTPUT:
    
1 . Interval development of mild pulmonary interstitial edema and moderate bilateral pleural effusions . 2 . Heterogeneous airspace opacification at the right base likely represents asymmetric edema and atelectasis , pneumonia not excluded . Follow up radiographs after the resolution of edema would be helpful .
