Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a persistent left pleural effusion with associated volume loss , not significantly changed from the prior exam . A small right linear consolidation is likely atelectasis in the setting of lower lung volumes . Again , diffuse interstitial abnormalities are present . There is no pneumothorax . The cardiomediastinal silhouette is unchanged . The size of the heart is somewhat difficult to evaluate given the volume loss and adjacent effusion .
    OUTPUT:
    
1 . No significant change in the left lower lobe volume loss and small - to - moderate left pleural effusion . 2 . Stable interstitial abnormalities which may be related to COPD , although pulmonary fibrosis is a consideration . If clinically indicated , could better evaluate with a CT of the chest .
