Abstract

Intraneural perineurioma is a benign tumor developed from the perineurium and responsible for localized nerve hypertrophy. This uncommon tumor is characterized by a proliferation of perineural cells with a "pseudo-onion bulb" pattern. We report a sciatic nerve intraneural perineurioma in a 39-year-old patient.

Keywords: EMA; Intraneural perineurioma; Nerf sciatique; Périneuriome intraneural; Sciatic nerve.
