    INPUT: Heterogeneous consolidation within the mid - to - upper left lung corresponds with opacity of concern on prior chest CT , suspicious for reccurrence of malignancy . Additional concerning nodules seen on prior CT are not well characterized on this radiographic examination . Linear opacities in the lung bases and right mid lung likely reflect areas of subsegmental atelectasis . Prominence of the interstitium is likely related to technique . No overt pulmonary edema is evident Blunting of the bilateral costophrenic angles may be due to small bilateral pleural effusions . Cardiomediastinal and hilar contours are within normal limits .
    OUTPUT:
