Abstract
- Most extracranial schwannomas are solitary, and schwannomas that occur within the context of neurofibromatosis tend to be multiple. But multiple schwannomas without any evidence of neurofibromatosis Type2 manifestation are very rare. A 49-year-old woman suffered from motor weakness and long standing low back pain and sciatica. Cervical spine MRI showed a dumbbell- shaped mass, extending from craniovertebral junction to C1, C2 spinal canal. Lumbar spine MRI showed intradural masses at L3 and L4~L5 levels. There were no clinical and radiological manifestation of Type2 neurofibromatosis. We removed these multiple tumor masses simultaneously by operation. Histologically confirmed diagnosis were all schwannomas.
