A biopsy of the sacral mass was performed and histological analysis confirmed a diagnosis of chordoma.

The patient underwent multiple consecutive surgeries to facilitate resection of the chordoma and subsequent reconstruction of skeletal and soft tissue structures. Initially, a laparotomy with stoma formation was performed. Following this, in order to resect the chordoma, a total sacrectomy was performed followed by spinopelvic fixation. Finally, the soft tissue defect was reconstructed with bilateral gluteus maximus and erector spinae advancement flaps.
