Mild bibasilar atelectasis is noted in the setting of low lung volumes . No significant pleural effusion , focal consolidation or pneumothorax is detected . The cardiomediastinal and hilar contours are within normal limits allowing for low lung volumes . There is no free air beneath the right hemidiaphragm .
    OUTPUT:
    
1 . No acute , displaced rib fracture detected . If there is persistent pain and clinical concern , a dedicated rib series is recommended with a BB overlying the area of patient 's tenderness . 2 . Bibasilar atelectasis in the setting of low lung volumes .
