Percutaneous radiofrequency ablation for treatment of giant cell tumor of bone guided by real-time US fused with CT

Radiofrequency ablation (RFA) is a well-established technique for the treatment of soft tissue tumors of the liver and kidney that has increasingly been used for both benign and malignant bone tumors, such as giant cell tumor of bone (GCT). Reports in the literature pertaining to RFA for GCT have involved computed tomography (CT)-guided RFA, which presents several drawbacks such as radiation, lack of real-time monitoring, and the fact that it may be time-consuming. We report a case of GCT treated with percutaneous RFA using ultrasound guidance with CT fusion, which offers a simple, real-time guidance solution without radiation.
