    INPUT: A temporary dialysis catheter as no been exchanged for a tunneled right internal jugular catheter . The tip is in the right atrium . Compared to the prior study there is improved aeration of the bilateral lungs with resolution of the frank pulmonary edema . There is persistent prominence of the pulmonary vasculature consistent with fluid overload . There is linear atelectasis of the bilateral lung bases . An airspace opacity adjacent to the right heart border may reflect atelectasis versus consolidation .
    OUTPUT:
    
Pulmonary vascular congestion without frank pulmonary edema . Atelectasis versus infection at the right lung base .
