Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left chest wall Port - A - Cath is again seen with catheter tip in the right atrium . Blunting of lateral costophrenic angles suggest small effusions as seen on prior . Increased bibasilar opacities are seen potentially due to atelectasis although developing infection is possible . More dense retrocardiac opacity silhouetting the descending thoracic aorta may represent infection . These findings are superimposed on diffuse increased interstitial markings which may represent edema . Cardiomediastinal silhouette is within normal limits .
    OUTPUT:
    
Bilateral pleural effusions and increased interstitial markings suggesting edema as on prior . Increased bibasilar opacities with more dense retrocardiac opacity silhouetting the hemidiaphragm may represent superimposed infection versus atelectasis . Consider PA and lateral views for better characterization .
