    INPUT: The heart size is top normal . The mediastinal contour is unchanged . Right hilar lymphadenopathy appears similar when compared to the prior studies .

There is no acute osseous abnormality including a displaced rib fracture identified .
    OUTPUT:
    
1 . No displaced rib fracture identified . If there is continued concern for a rib fracture , then a dedicated rib series is recommended . 2 . Right hilar lymphadenopathy persists , and differential considerations remain broad including inflammatory , infectious , or neoplastic etiologies as noted on the prior chest CT . Continued clinical workup and followup is recommended if not already in progress . Previously seen right lower lobe patchy opacities have improved .
