SUMMARYMobile intraspinal tumours have rarely been reported. In most cases, mobile tumours such as schwannomas or ependymomas were located in the cauda equina. Perusal of the literature revealed only two reports of mobile schwannomas in the cervical and thoracic regions. We report a case of thoracic schwannoma which migrated twice in successive operations resulting in negative exploration in the expected area. The aim of this report is to remind the surgeons about the possibility of migration of intradural-extramedullary tumour. BACKGROUND

“…To prevent missing tumors, reexamination by preoperative MRI [4] procedure has some problems. Routine application of MRI a second time is costly, intraoperative ultrasonography must be performed after laminectomy, and the tumor may move after infusion of contrast medium and postural change during the intraoperative myelography.…”

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.

“…There have been few cases of where cervical tumor have migrated to thoracic levels. Lizuka et al (16) in 1998 have reported a case where the initial tumor location was involving C7-T1 vertebral level and had migrated to T1-T2 level with vertebral discrepancy of one vertebral level. They used intra-operative MRI as well as myelography to localize the tumor intraoperatively.…”

Background: Although rare, mobile schwannomas have been observed at various vertebral levels. Most of them have been reported within the lumbar spine or thoracic spine. We report a rare case of mobile schwannoma of high cervical spine and only two cases of such in cervical spine have been reported in literature. Case description: We report case of young lady with high cervical spine schwannoma (C3-C4) on preoperative MRI imaging. Intra-operatively to our surprise we could not find the tumor at C3-4 and had migrated cranially upto C2-3. Partial C2 laminectomy was done to excise the tumour completely. She recovered with no deficit. Conclusion: Mobile cervical tumors are a rare entity. There are many predisposing factors for tumours to migrate. In our case we presume that prone positing along with slight flexion may have caused the tumour to migrate cranially. One should always be prepared for negative exploration.
