    INPUT: Right - sided IJ introducer catheter is present , with the tip in the right brachiocephalic / SVC junction . Endotracheal tube remains in place , with the tip approximately 5 cm above the carina . NG tube remains in place , extending into the stomach . There is persistent left retrocardiac opacity , presumably representing changes of atelectasis . There is a small - to - moderate persistent left - sided pleural effusion , probably with some regions of loculation given some well - circumscribed opacities at the left lung base , which is probably fluid within the major fissure . There are no new focal pulmonary opacities , pleural effusions , or evidence of pneumothorax . There is probably some scarring seen at the lung apices .
    OUTPUT:
    
Bilateral pleural effusions , slightly greater on the left than on the right , with essentially unchanged examination since one day previously .
