Abstract

|
Multiple schwannomas without vestibular schwannomas (schwannomatosis) are new classification of neurofibromatoses. Understanding of this disease entity is emerging, recently. We experienced a case of schwannomatosis, and reviewed some literatures related to schwannomas. A 45-year-old woman visited our hospital with low back pain and radiating leg pain. The patient’s spine MR images revealed that she had multiple intradural extramedullary masses in lumbar spinal canal, extending to paravertebral space through neural foramen. On brain MR images, there were no vestibular schwannomas. We took a operation to resolve her symptoms. After we removed the intradural extramedullary masses in lumbar spinal canal, her symptoms were improved.
