Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest were obtained . There are increased interstitial markings at the bilateral bases , more prominent on the right than the left . This is likely attributable to some underlying lung disease , but given the change from the prior CT , also likely represents mild pulmonary edema . The upper lung zones are relatively hyperlucent due to the severe emphysematous disease . There are small bilateral pleural effusions , slightly larger on the right than the left . There is no pneumothorax . The cardiomediastinal silhouette is normal . Atherosclerotic calcifications are noted in the aortic arch .
    OUTPUT:
    
1 . Increased interstitial markings at the bilateral bases is likely due to mild pulmonary edema superimposed on underlying lung disease . 2 . New small bilateral pleural effusions . 3 . Severe emphysematous disease .
