    INPUT: A chest tube remains in the right hemithorax . This study shows reaccumulation of a pleural effusion on the right , probably small to moderate in size , with volume loss and opacity probably due to increasing atelectasis . Left basilar opacification appears similar to minimally improved . Perihilar congestion is new . Nondisplaced right third through fifth , and potentially sixth rib fractures , appear unchanged although the fourth rib fracture is better visualized on this study .
    OUTPUT:
    
Recurring right - sided pleural effusion with opacity probably due to atelectasis . Findings suggest new mild vascular congestion .
