Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Interstitial opacities predominantly within the lung bases appear similar compared to prior examination and correspond with known bronchiectasis . Mild prominence of the upper lung vasculature suggests new superimposed vascular congestion ; however , there is no overt edema or large effusions . No confluent consolidation is identified . Cardiomediastinal and hilar contours are within normal limits . No pneumothorax is evident . Healed right - sided rib fractures are unchanged from prior .
    OUTPUT:
    
1 . Stable basilar interstitial markings consistent with known bronchiectasis . No superimposed confluent consolidation . 2 . Mild pulmonary vascular congestion though no overt edema or large effusions .
