    INPUT: Endotracheal tube tip projects over the low trachea approximately 2 .5 cm above the carina . An esophageal catheter traverses below the diaphragm with tip projecting over the left upper quadrant , likely within the stomach . There is a small left pleural effusion . Patchy opacity at right cardiophrenic angle and vertical stranding at left base medially most likely represents atelectasis or scarring . No focal consolidation or pneumothorax is detected on this single view . Heart size is top normal . Aortic tortuosity is seen with otherwise normal mediastinal contours .
    OUTPUT:
    
1 . Endotracheal tube tip projecting over the low trachea . 2 . Small left pleural effusion . 3 . Bibasilar atelectasis or scarring . Attention to right cardiophrenic angle opacity is recommended to exclude early infiltrate .
