    INPUT: The patient has been intubated . The endotracheal tube terminates approximately 4 cm above the carina . Vascular pedicle seems widened which is probably due to some degree of fluid overload . Marked opacification of each mid to upper lung is suggestive of pulmonary edema . Differential diagnoses include acute respiratory distress syndrome or widespread multifocal pneumonia . A coinciding opacity at the left lung base may be due to atelectasis or pneumonia . There is no definite pleural effusion or pneumothorax .
    OUTPUT:
    
Status post endotracheal intubation . Extensive lung opacification .
