CTICasesPleurX Catheter Site Infection
Imaging findings
CT in a patient with a malignant effusion shows fluid tracking around the pleural drainage catheter in the chest wall, associated with soft tissue stranding, gas bubbles, and cellulitis at the entry site, representing catheter tract infection.
Key takeaways
Indwelling tunneled pleural catheters (PleurX) can become infected. Radiologists should follow the catheter tract through the chest wall on CT to look for fluid accumulation, gas, and cellulitis, which represent tract infections.
