Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: While opacities in the right lower lobe are consistent with post operative changes , these appear to be denser than on prior exams , arguing for a superimposed infection . A right - sided Port - A - Cath terminates in the lower SVC , possibly extending into the right atrium . Left lung is essentially clear with the exception of mild basilar atelectasis . Cardiomediastinal silhouette and hilar contours are unremarkable .
    OUTPUT:
    
On top of the post operative changes in the right lower lobe , there is likely a superimposed infectious process .
