    INPUT: The ET tube is in adequate position . The NG tube is in adequate position . There is mild pulmonary edema , right greater than left . Emphysema is likely . Greater right upper pleural thickening on the costal and mediastinal surfaces compared with prior exams suggests local tumor recurrence , perhaps involving mediastinal nodes and right hilus impinging on the bronchial tree . No pneumothorax is seen .
    OUTPUT:
    
1 . ET tube and NG tube in appropriate positions . 2 . Mild pulmonary edema , right greater than left . 3 . Chest CT would help assess possible right hilar , mediastinal and pleural tumor recurrence . 4 . Emphysema .
