Abstract
Introduction: Schwannomas are usually benign tumors arising from Schwann cells of peripheral nerve sheaths. They are rarely located in the retroperitoneum and usually incidentally diagnosed. Sciatic nerve involvement is unusual.
Case Report: We report a case of schwannoma of the right sciatic nerve in a 39-year-old female with an incidental diagnosis. Magnetic resonance imaging (MRI) scan showed a 4.5 cm sciatic nerve dependent lesion located in the right pelvic region. Surgical complete resection of the lesion was performed. Final histopathological exam revealed the tumor to be a schwannoma.
Conclusion: Schwannoma of the sciatic nerve can cause a pain in the lower limb similar to chronic sciatica. Magnetic resonance imaging (MRI) scan is helpful in the differential diagnosis. Histopathological examination gives definitive diagnosis.

Keywords: Schwann cells, Schwannoma, Sciatic nerve
