Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is somewhat rotated on today 's study which limits assessment . The endotracheal tube and nasogastric tube are grossly unchanged in position . The left - sided internal jugular catheter appears to terminate in the left brachiocephalic vein . Previous median sternotomy noted with unchanged appearances of the sutures . There is a hazy opacity at the right lung base consistent with a layering effusion . Small left pleural effusion also seen . Bilateral lower lobe atelectasis , unchanged compared to the prior study . Superimposed infection can not be excluded . An apparent superior mediastinal mass is likely an artifact as this is related to tubing overlying the patient attention on followup recommended .
    OUTPUT:
    
No significant interval change when compared to the prior study .
