    INPUT: There is increased opacity in the right perihilar region . The right cardiac margin is not clearly identified on the frontal view . While this may be partially due to rotation , given subtle increased opacity on the lateral view projecting over the cardiac silhouette underlying right middle lobe consolidation is likely present . Elsewhere , the lungs are clear . Median sternotomy wires are intact . Cardiomediastinal silhouette is otherwise unremarkable . No acute osseous abnormalities .
    OUTPUT:
    
Right middle lobe opacity which could be in part due to scarring given prior findings although superimposed infection would certainly be possible .
