    INPUT: The patient is slightly rotated to the right on this portable frontal chest radiograph . Bilateral pleural effusions appear increased compared with priors . There is emphysema and increasing interstitial abnormality within the right lung more than the left . The heart size remains normal , note is made of marked mitral annular calcification . Opacity projecting behind the heart likely reflects a fluid - filled hiatal hernia . There is no pneumothorax .
    OUTPUT:
    
1 . Increasing interstitial abnormality within the lungs , right greater than left , most likely reflects asymmetric edema , though pneumonia is not excluded . 2 . Hiatal hernia .
