Combined computed tomography-guided radiofrequency ablation and brachytherapy in a child with multiple recurrences of Wilms' tumor.

Background: Treatment of relapsed Wilms' tumor remains a challenge. We describe a case of an 11-year-old girl with multiply relapsed Wilms' tumor in whom combined percutaneous computed tomography (CT)-guided radiofrequency ablation and brachytherapy directed at a retroperitoneal tumor mass resulted in pain palliation and local tumor control.

Observations: Over the course of few weeks, her requirement for narcotic pain medications dramatically decreased.
