Abstract

Three-dimensional planning of in-situ (trans-sacral) image guided cryoablation provides a method to treat sacral GCTs that accommodates the intricacies of the pelvis offering a safer, more efficacious alternative. Here we report on IM a 23-year-old female with a sacral GCT. She presented to Tel Aviv Medical Center with ongoing pain as well as neurological symptoms. For six years, the patient was in-and-out of the hospital for Denosumab treatment and recurrent infections. Eventually, further treatment became necessary, and she was treated with image guided cryoablation. By six months follow-up, the patient was mobile and pain-free.
