    INPUT: Assessment is limited by rotation . Cardiac silhouette size remains moderately enlarged , but unchanged . Mediastinal and hilar contours are relatively similar . Previously noted mild interstitial pulmonary edema has essentially resolved . There is continued opacification in the right lung base likely reflective of a combination of a small right pleural effusion and right basilar atelectasis . Infection is not completely excluded in the correct clinical setting . No additional focal consolidation is seen . There is no pneumothorax . Moderate multilevel degenerative changes are noted in the thoracic spine .
    OUTPUT:
    
Right basilar opacification , not substantially changed in the interval , likely a combination of small right pleural effusion and right basilar atelectasis . Infection is difficult to exclude in the correct clinical setting .
