Efforts from many different approaches have been made to manage malignant sacral pain that commonly occurs in cancers from pelvic origin.

Radiofrequency sacral rhizotomy is a new method for the relief of the sacrococcygeal pain. We report a case in which we managed a patient with malignant sacrococcygeal pain with radiofrequency thermocoagulation.
