Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size remains mildly enlarged . A moderate size hiatal hernia is similar . Mediastinal and hilar contours are unchanged . Diffuse airspace opacities are noted bilaterally with relative sparing of the lung bases , worse compared to the previous examinations . There may be an element of mild pulmonary vascular congestion . There appears to be a trace left pleural effusion . No pneumothorax is identified . Deformity of the right mid clavicle is compatible with a remote fracture . Remote compression deformity of the L1 vertebral body is also unchanged . There are no acute osseous abnormalities . Loose body adjacent to the left glenohumeral joint is again noted .
    OUTPUT:
    
1 . Diffuse airspace opacities bilaterally , worse compared to the most recent chest radiograph . Findings may reflect multifocal pneumonia in the correct clinical setting . Alternatively , this could reflect worsening of the patient 's presumed cryptogenic organizing pneumonia . 2 . Possible element of mild pulmonary vascular congestion and trace left pleural effusion .
