Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well expanded . There are patchy opacities in the left lower lung region as well as in the right lower lung , more prominently in the right cardiophrenic angle which appear new or more conspicuous than on the previous examination . No other focal opacities are identified . Bilateral apical pleural parenchymal scarring is present . Cardiomediastinal and hilar contours are unremarkable . Significant atherosclerotic calcifications of the aortic knob are present . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Interval development of patchy bibasilar opacities is compatible with multifocal pneumonia . The increased conspicuity in the short interval is likely related to full manifestation of the inflammatory process after administration of IV fluids .
