Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is within normal limits . The mediastinal contours are within normal limits and unchanged . The lungs demonstrate retrocardiac opacities as well as an opacity at the right cardiophrenic angle . An area of linear atelectasis in the right mid lung has progressed or perhaps this opacity may represent fluid in the minor fissure . A widespread mild - to - moderate interstitial abnormality involves the right lung with sparing of the left mid and upper lung . Blunting of both costophrenic angles suggest small bilateral pleural effusions . There is no pneumothorax .
    OUTPUT:
    
Bibasilar opacities most suggestive of pneumonia in the appropriate clinical setting ; noting widespread interstitial changes in the right upper lung compared to the left , the possibility of asymmetric edema with bibasilar atelectasis could be considered but seems less likely . Small bilateral pleural effusions .
