Résumé
Intramedullary spinal schwannomas constitute only 0.3% of primary spine tumors. We could identify only 13 such cases involving the conus that were not associated with neurofibromatosis (NF). Here, we report a 70-year-old male without NF who was found to have a paraparesis due to a schwannoma of the thoracolumbar junction/conus (D11-L2). A 70-year-old male presented with an L1-level paraparesis with urinary incontinence. The magnetic resonance showed an intramedullary mass of 85 × 10 mm extending from D11 to L2; it demonstrated significant patchy enhancement. The patient underwent a D12 and L1 laminectomy with gross total excision of the mass that proved to be a schwannoma. Three months postoperatively, he was able to ambulate with support, and regained sphincter function. Intramedullary schwannomas involving the conus/thoracolumbar junction are rare, and can be successfully excised resulting in good outcomes.

BACKGROUND
BACKGROUND
Intramedullary spinal schwannomas constitute only 0.3% of primary spine tumors. We could identify only 13 such cases involving the conus that were not associated with neurofibromatosis (NF). Here, we report a 70-year-old male without NF who was found to have a paraparesis due to a schwannoma of the thoracolumbar junction/conus (D11-L2).
CASE DESCRIPTION
METHODS
A 70-year-old male presented with an L1-level paraparesis with urinary incontinence. The magnetic resonance showed an intramedullary mass of 85 × 10 mm extending from D11 to L2; it demonstrated significant patchy enhancement. The patient underwent a D12 and L1 laminectomy with gross total excision of the mass that proved to be a schwannoma. Three months postoperatively, he was able to ambulate with support, and regained sphincter function.
CONCLUSION
CONCLUSIONS
Intramedullary schwannomas involving the conus/thoracolumbar junction are rare, and can be successfully excised resulting in good outcomes.
