Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: New compared to prior bilateral hazy perihilar opacities . Better seen on the lateral view is a focal rounded opacity projecting posteriorly , overlying the lower lobes , likely localizing to the right on the frontal view . Additional nodular opacity projects over the anterior right third rib laterally , new since prior . It is uncertain if this is due to rib changes or underlying parenchymal abnormality . There is no large pleural effusion . Cardiomediastinal silhouette is within normal limits . Median sternotomy wires are intact . No acute osseous abnormalities
    OUTPUT:
    
Bilateral perihilar opacities new since prior potentially due to edema , infection and / or malignancy in light of patient 's history . More focal opacity projecting over the lower lobes on the lateral view , likely on the right based on the frontal which could correlate with known malignancy . Additional opacity projecting over the anterior right third rib could be due to rib changes or underlying parenchymal abnormality . Correlation with cross - sectional imaging , presumably performed elsewhere is suggested for further characterization of these findings . Otherwise , additional cross - sectional imaging will be necessary .
