Robot-Assisted Radiofrequency Ablation of a Sacral S1-S2 Aggressive Hemangioma.

Abstract

Aggressive vertebral hemangiomas are rare tumors of the spine. The treatment management strategy usually consists of vertebroplasty, radiation therapy, or, in rare cases of surgical strategy. We present a case of a bulging sacral S1-S2 hemangioma in the spinal canal that could not be managed in the usual manner. Here we demonstrate the usefulness of radiofrequency ablation technique as an alternative treatment, as well as robotic assistance for optimal placement of the ablation probe within the lesion.
