Total sacrectomy for low-grade malignant peripheral nerve sheath tumour: a case report.

We report on a 58-year-old woman who underwent total sacrectomy and spinopelvic reconstruction for a low-grade malignant peripheral nerve sheath tumour involving the sacrum. One week later, she developed deep wound infection, and the entire spinopelvic reconstruction was removed. At the 36-month followup, the patient had no pain and was able to walk with a walking frame. There was no sign of recurrence or metastasis.
