CTICasesPAPVR Cannulated by Dialysis Catheter
Imaging findings
Chest radiograph shows a left-sided dialysis catheter with its tip projecting laterally. CT and venogram show the catheter tip located within an anomalous right superior pulmonary vein draining into the SVC (PAPVR).
Key takeaways
Right upper lobe PAPVR typically drains into the SVC. Catheters placed from the left side can inadvertently enter this anomalous vein, which is diagnosed by noting the lateral project of the catheter tip on radiographs.
