Plexiform schwannomas of the sciatic nerve: a case report and review of the literature

Background: Plexiform sciatic schwannoma is a rare tumor.Schwannoma is deceptive when it appears on the sciatic nerve. We report a rare case of plexiform sciatic schwannoma that was initially diagnosed as a lumbar disease. Case Presentation: A 43-year-old female complained of pain in her low back and left thigh for 10 years.Physical examination and MRI confirmed that she had a rare plexiform sciatic schwannoma.After obtaining the patient's consent, we performed intracapsular excision of her tumor.The patient recovered well after operation and there was no sign of nerve injury. Conclusions: : Schwannomas in the sciatic nerve are misleading and doctors should pay attention to physical examination and MRI.Intracapsular excision is the best treatment for schwannomas.
