    INPUT: PA and lateral radiographs of the chest demonstrate an increase in pleural fluid tracking along the major fissure on the right which may represent redistribution but a total increase in effusion is not excluded . A small amount of pleural air persists at the right base next to a pleural drainage catheter . Bilateral lower lobe atelectasis persist . Moderate cardiomegaly is stable . The hilar and mediastinal contours are unchanged .
    OUTPUT:
    
1 . Redistribution of pleural fluid along the major fissure on the right , with possible overall increase in the extent of effusion . 2 . Persistent pleural air adjacent to catheter . 3 . Unchanged bilateral lower lobe atelectasis .
