Summary
Extradural spinal schwannomas are rare tumors. Early diagnosis and complete surgical resection of these benign nerve sheath tumors lead to an excellent prognosis.
Area of Science:
- Neurosurgery
- Oncology
- Spinal Cord Research
Background:
- Schwannomas are benign nerve sheath tumors arising from Schwann cells.
- Intraspinal schwannomas account for 30% of primary spinal neoplasms.
- Extradural schwannomas are rare, representing approximately 15% of intraspinal cases.
Observation:
- This report details two adult males with symptomatic extradural thoracic schwannomas.
- Patients presented with paraparesis, low back pain, and spasticity.
- Spinal MRI revealed extradural mass lesions at the T1-T2 and T4-T6 levels.
Findings:
- Extradural schwannomas, though rare, can cause significant neurological deficits.
- Surgical resection is the primary treatment modality.
- Complete tumor removal via hemilaminectomy resulted in a favorable outcome.
Implications:
- Prompt diagnosis and surgical intervention are crucial for optimal outcomes in spinal schwannoma cases.
- Understanding the rare extradural location is important for surgical planning.
- Early treatment can prevent severe neurological symptoms and ensure an excellent prognosis.
