Summary
A rare sciatic nerve schwannoma caused sciatica in a 69-year-old female. Early diagnosis and surgical removal of this nerve tumor can fully resolve sciatica symptoms.
Area of Science:
- Neurology
- Oncology
Background:
- Sciatica is a common condition often caused by lumbar disc prolapse.
- Schwannomas are typically benign nerve sheath tumors, but sciatic nerve schwannomas are rare.
Purpose of the Study:
- To report a rare case of sciatic nerve schwannoma presenting as sciatica.
- To highlight the importance of considering sciatic nerve schwannoma in differential diagnosis.
Main Methods:
- Case report of a 69-year-old female patient.
- Clinical presentation, diagnostic workup, and surgical management were reviewed.
Main Results:
- The patient presented with sciatica symptoms.
- No lumbar disc prolapse or positive crossed straight leg raise test was found.
- A sciatic nerve schwannoma was diagnosed and surgically excised.
Conclusions:
- Sciatic nerve schwannoma is a rare but important cause of sciatica.
- Consideration of this diagnosis is crucial in patients with sciatica and negative findings for disc prolapse.
- Complete excision of the schwannoma leads to symptom resolution.
