Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: It appears that there are two successive radiographs presented for evaluation . The first is acquired at 7 :09 a .m . , the second at 7 : 12 a .m . An overlying trauma board obscures parts of the patient . The initial radiograph demonstrates a right main stem intubation . On the second radiograph , the ET tube has been retracted slightly but continues to reside in the right mainstem . Right - sided IJ terminates in appropriate position . Hyperlucent left hemithorax with deep sulcus suggests pneumothorax . Dense right - sided parenchymal opacities are probably a combination of atelectasis and aspiration ; pneumonia should be considered as well . There is a right - sided pleural effusion . The heart size is normal . Aortic calcifications are noted . Multiple left - sided rib cage deformities worrisome for fractures are noted .
    OUTPUT:
    
1 . Probable large left - sided pneumothorax with multiple left - sided rib deformities . 2 . ET tube continues to reside in the right mainstem bronchus even status post retraction . 3 . Large right - sided parenchymal opacity consistent with a combination of atelectasis , aspiration and possibly pneumonia . Also small right - sided pleural effusion . Please correlate findings with the subsequent chest CT . By the time of review of this radiograph , a subsequent radiograph demonstrated ET tube above the carina and left sided chest tube .
