Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest were reviewed . The cardiomediastinal and hilar contours are stable . Again noted is a left pacemaker with leads terminating in the right atrium and right ventricle as expected . There is no pneumothorax . There is a small right pleural effusion with atelectasis . Underlying consolidation at the right lung base can not be excluded . There is no left pleural effusion . Slight increase in interstitial markings diffusely may represent interstitial edema versus an atypical infection .
    OUTPUT:
    
1 . Right pleural effusion with atelectasis . Underlying consolidation at the right lung base can not be excluded . 2 . Slightly increased interstitial markings , which may represent interstitial edema versus atypical infection .
