Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Mild cardiomegaly is unchanged . The mediastinal and hilar contours are stable . There is no pulmonary edema . Small bilateral pleural effusions , larger on the left , are slightly decreased in size compared to the prior exam . Streaky opacity in the right lung base and a more focal consolidative opacity in the left lung base likely reflect areas of compressive atelectasis though infection can not be completely excluded . Calcified granuloma in the right mid lung field is unchanged . There is no pneumothorax . No acute osseous abnormalities demonstrated .
    OUTPUT:
    
Small bilateral pleural effusions , minimally improved compared to the previous exam with bibasilar airspace opacities likely reflective of atelectasis though infection is not excluded .
