Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is complete opacification of the left hemi thorax . In combination with left - sided volume loss and surgical clips , findings are suggestive of prior left pneumonectomy . Endotracheal tube tip is approximately 2 .8 cm from the expected region of the carina which is not well visualized . Hazy opacity projects over the right lung . This could represent a combination of infection edema or layering effusion . Right - sided central venous catheter projects to the left of midline , exact location is difficult to assess given altered anatomy . Cardiac silhouette for similar reasons can not be assessed . No acute osseous abnormalities .
    OUTPUT:
    
ET tube likely in appropriate position although delineating anatomic detail is difficult as detailed above . Probable prior left pneumonectomy . Right - sided parenchymal opacities could represent edema and / or infection .
