Recurrent Sacral Chordoma Treated by Radiotherapy: A Case Report

Chordoma is a rare and locally aggressive tumor that arises from the notochordal remnants that corresponds to 1 to 4 % of all malignant bone tumors in the axial skeleton, and has an incidence of 0.1/100000 per year. It consists of a silent and slow-growing mass that requires radical treatment due to its high potential for local and metastatic invasion. It is typically managed with surgery in combination with radiation therapy. The risk of recurrence is very high due to the infiltrating nature of the tumor. A favorable outcome depends on early diagnosis and surgical resection with tumor-free margins. It can arise along the ventromedial aspect of the sacrum, mobile spine, and clivus, with most cases occurring in the sacrum or skull base. We report a case of a 56-years male who complained of pain over his sacral region for the past three years and constipation with no neurological signs. Eighteen months after undergoing large surgery resection for his sacral chordoma with no adjuvant treatment. He was then diagnosed with recurrent sacral chordoma and planned for radiotherapy given the possible complications after surgery.
