Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since prior exam , the patient has undergone a right thoracentesis . The right pleural effusion has nearly completely resolved . Patchy interstitial opacity at the right base likely represents some reexpansion edema and residual atelectasis . There is no evidence of pneumothorax . A small left pleural effusion appears slightly larger than on the prior exam from earlier this morning . Left basilar consolidation is likely atelectasis . Other patchy bilateral opacities are unchanged , and consistent with the known pneumonia . The cardiomediastinal silhouette is normal .
    OUTPUT:
    
1 . Significant interval decrease in size of the right pleural effusion . No evidence of pneumothorax . 2 . New right basilar consolidation is likely some reexpansion pulmonary edema . 3 . Slight interval enlargement of small left pleural effusion with associated atelectasis .
