Sciatic Schwannoma in a Patient with Neurofibromatosis Type 1: A Report of a Minimally Invasive Surgical Technique and Review of the Literature.

Schwannomas rarely occur in patients with neurofibromatosis type 1 (NF1). A sciatic schwannoma (SS) is the cause of sciatica in less than one percent of cases. These tumors are traditionally resected by the transgluteal approach, gaining access to the tumor through a large incision. Herein, we report a minimally invasive resection of an SS in a patient with NF1, who presented with typical sciatica four months after resection of a lumbar schwannoma. The clinical and imaging characteristics of these tumors are also reviewed.
