Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac , mediastinal and hilar contours appear stable . There is a dense consolidation involving the right middle lobe , as before . There are also extensive opacities in the right upper lobe as well as more patchy distribution of nodular opacities in the left lung . Allowing for differences in technique , there is increased diffuse interstitial abnormality but otherwise probably no recent change .
    OUTPUT:
    
Findings consistent with metastatic disease including lymphangitic carcinomatosis and nodules ; however , mild to moderate diffuse superimposed interstitial abnormality is suspected and could be seen with pulmonary edema or perhaps atypical infectious process in the appropriate setting .
