Schwannome du nerf sciatique (à propos d’un cas)
2020
Schwannomas of the sciatic nerve are rare tumors. They are mainly manifested by sciatic neuralgia rather than by sensory-motor deficits. We report the case of a 30-year-old female patient with right buttock pain for 1 year. Palpation revealed a positive Tinel sign. A magnetic resonance imaging (MRI) was performed which objectified a roughly rounded, regular mass of 2 cm in diameter in intimate contact with the large sciatic nerve. A complete excision of the tumor was carried out. This excision allowed the pain to disappear and the pathology examination concluded with a plexiform schwannoma.
