    INPUT: Chronic severe right middle lobe atelectasis is again seen . The lungs remain hyperinflated . Widespread coarse reticular opacities reflect chronic interstitial disease . A small peripheral right middle zone opacity appears slightly denser , which may reflect atelectasis or new small consolidation . Trace bilateral pleural effusions are unchanged . There is no pneumothorax . The heart size remains normal .
    OUTPUT:
    
1 . Slightly increased density of a peripherally - based right middle zone opacity may represent a new consolidation versus atelectasis . 2 . Unchanged hyperinflation and coarse reticular opacities denoting chronic interstitial disease . 3 . Unchanged severe right middle lobe atelectasis .
