title: Palliation of recurrent Ewing sarcoma of the pelvis with cryoablation and somatosensory-evoked potentials.
abstract: Palliation of recurrent Ewing sarcoma can be difficult to treat due to tumor resistance to chemotherapy and previously received maximum dose radiotherapy. We report the successful use of cryoablation for pain palliation in a patient with recurrent pelvic Ewing sarcoma. Tumor location necessitated use of somatosensory-evoked potentials to prevent nerve damage to the S1 nerve root. Clinical and imaging aspects of the case are discussed.
