Modality: X-ray

Right internal jugular vein permacath with distal tip at the cavo-atrial junction. No pneumothorax. Well-defined but slightly lobulated opacity in the peripheral left lower zone.

Case Discussion

Permacaths (or permcaths) are a type of tunneled central venous catheter. It is a split catheter - this means that the two lumens have unequal lengths with one opening a few centimetres distal to the other giving a staggered or step tip appearance. It is often used for haemodialysis.
