Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison with chest radiograph from ___ , small bilateral effusions are minimally improved . New consolidation at the left lung base with associated air bronchograms suggests atelectasis or pneumonia . Mild interstitial pulmonary edema is more prominent on the right , though this is likely reflective of positional differences and total volume is unlikely significantly changed . No pneumothorax . Mediastinal and hilar contours are stable . Mild cardiomegaly is unchanged .
    OUTPUT:
    
1 . New consolidation at the left lung base with associated air bronchograms suggests atelectasis or pneumonia . Recommend correlation with physical exam and laboratory results . 2 . Small bilateral pleural effusions . 3 . Stable mild interstitial pulmonary edema . 4 . Unchanged mild cardiomegaly .
