Abstract
- Sacral schwannoma is a rare lesion with a tendency to reach large proportions. The authors report a case of giant intrasacral schwannoma in a 49-year-old man who had persistent lumbago and sciatica over 15 years period. Plain spine X-ray revealed destruction of the sacrum and myelogram demonstrated a complete ampu-tation of the lumbosacral cul-de-sac at the L5/S1 level. CT and MRI showed a destructive mass lesion within the upper part of sacrum with a large mass extending into the presacral space. The patient underwent su rgery consisted of posterior lumbosacral laminectomy and subtotal removal of tumor. Pathologic examination revealed a benign schwannoma. The patient returned to work 1 month postoperatively with improvement of symptoms. Characteristics of this case with a pe rtinent literature are reviewed.
