Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well expanded . The cardiomediastinal silhouette is within normal limits . Known mediastinal and hilar nodes are not well appreciated radiographically . Left - sided pacemaker with lead tips over the right atrium and right ventricle noted . Multiple nodules an opacities seen on the chest CT from ___ are poorly visualized by radiograph . On today 's exam , there is a faint small patchy opacity in the right mid zone laterally , above a slightly thickened minor fissure ; some patchy opacity at the right base , with blunting of the right costophrenic angle ; and minimal patchy opacity at the left base . Findings at the right base are more pronounced and could represent early superimposed pneumonic infiltrate . The right midzone left base opacities are similar to the prior film . The prominent rounded density previously seen over the right lower lung is no longer visualized and , itself , may have represented a nipple shadow .
    OUTPUT:
    
1 . Patchy opacity at the right base has increased compared with both the ___ radiograph and with targeted review of the ___ chest CT . This could therefore represent an early pneumonic infiltrate or possibly an early area of aspiration pneumonitis . 2 . Scattered irregular and nodular opacities are seen in both lungs , though the radiographic findings are much more subtle than on the recent CT scan .
