    INPUT: There is a coarse opacity involving the right lung that probably represents residual from a marked inflammatory process involving the right lung , as seen on earlier radiographs from ___ , having mostly resolved since that study ; however right lung opacities may be slightly more prominent than on the more recent prior study . Lesser residual changes are seen in the left mid lung . There is a small suspected residual left - sided pleural effusion . Bony structures are unremarkable . The patient is status post sternotomy .
    OUTPUT:
    
Vague multifocal opacities , similar to perhaps slightly more prominent than on the most recent prior study , although markedly improved since the earlier examination . This appearance does not represent a definite change and may correlate with residual mild opacification from a marked resolving inflammatory process . However , subtle recurrence of pneumonia is hard to exclude , and short - term follow - up radiographs may be helpful to evaluate further if pulmonary symptoms are present . No evidence for free air or pneumomediastinum .
