    INPUT: The distal aspect of a right - sided PICC is not as well seen as compared to the prior study . On this study , it appears to terminate at the proximal SVC / SVC - brachiocephalic junction and appears to have migrated proximally in the interval . No pneumothorax is seen . Since the prior study , there has been increase in bilateral perihilar and mid to lower lung opacities which could relate to fluid overload although infectious process is not excluded . No large pleural effusion is seen .

Distal aspect of a right - sided PICC is not as well seen as compared to the prior study . On this study , it appears to terminate at the proximal SVC / SVC - brachiocephalic junction , higher in position than on the prior , and appears to have migrated proximally in the interval . Since the prior study , there has been increase in bilateral perihilar and mid to lower lung opacities which could relate to fluid overload although infectious process is not excluded .
