Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal shadow is normal . There is a linear confluent airspace opacification ( most likely atelectasis ) seen in the basal aspect of the right lung with an associated effusion . Smaller left - sided effusion with adjacent subsegmental atelectasis . The upper lung zones are clear . No pulmonary edema . Spondylotic changes of the thoracic spine .
    OUTPUT:
    
Small bilateral pleural effusions with this adjacent atelectatic changes ( right more than left ) . Although I favor atelectasis to explain the airspace opacification in the right lung base , pneumonia can not be excluded with absolute certainty .
