Abstract
We report on a case of a mobile schwannoma of the cauda equina. The patient was a 24-year-old woman who visited our hospital with the chief complaints of low back pain and numbness of the right leg. A tumor was noted from the L2 midbody level to the L3 upper endplate on preoperative MRI and myelogram. During the surgery, a right L2 hemilaminectomy was performed, and the dura was incised, but no tumor was founded in the surgical field, and this was noted as a missing tumor. Intraoperative myelography showed that the tumor had moved to the adjacent vertebra on the caudal side. Myelography applied again to the caudal side of the mobile tumor. Then, the tumor had moved upward, and could be excised without an additional laminectomy.
