Inflammatory nodules mimic applicator track seeding after percutaneous ablation of renal tumors

AJR Am J Roentgenol. 2007 Oct;189(4):845-8. doi: 10.2214/AJR.07.2015.


Objective: The objective of our study was to report the occurrence of benign inflammatory nodules that develop in or near applicator tracks after percutaneous radiofrequency ablation and cryoablation of renal tumors.

Conclusion: Benign inflammatory nodules occur rarely after percutaneous ablation of renal tumors and may mimic tumor seeding of the applicator track.
