The Single Posterior Approach for Resection of Sacral Chordoma: A Case Report

Chordoma is a relatively rare primary malignant neoplasm that originates from ectopic notochordal cells, and most chordomas arise in the sacrococcygeal and clivus regions. Due to the poor response to adjuvant therapy, complete tumor resection is the treatment of choice. This case report describes a 57-year-old male patient who presented with a very large sacral chordoma involving the S2-S5 bodies, extending to the right piriformis and gluteal muscles. He was successfully treated with a single-stage posterior approach and was free of local recurrence at a 5-year follow-up examination, without neurological deficits. A single posterior approach is a feasible option for the treatment of sacral chordomas.
