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

## TL;DR

This paper describes a minimally invasive surgical technique for removing a sciatic schwannoma in a patient with neurofibromatosis type 1.

## Contribution

The novelty is the use of a minimally invasive approach for sciatic schwannoma resection in NF1.

## Key findings

- Sciatic schwannomas are rare in NF1 patients and typically cause sciatica in less than 1% of cases.
- A minimally invasive technique was successfully used for resection in this case.
- The clinical and imaging features of these tumors were reviewed.

## Abstract

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.
