Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac , mediastinal and hilar contours are unchanged , with the heart size within normal limits . There is no pulmonary vascular congestion . There is similar blunting of the right costophrenic angle which again may reflect a small pleural effusion or pleural thickening . Emphysematous changes are again seen within the lung apices . Streaky opacities in the lung bases likely reflect areas of atelectasis . Minimal patchy opacity is noted within the peripheral aspect of the right mid lung field which could reflect a developing area of infection . No pneumothorax is identified . No acute osseous abnormality is seen .
    OUTPUT:
    
Patchy opacity within the periphery of the right mid lung field could reflect an area of developing infection . Similar blunting of the right costophrenic angle , which could be suggestive of a small pleural effusion or pleural thickening . Mild bibasilar atelectasis .
