The discrepancy between the myelographic and the operative locations of the tumor, which is allowed by a redundant nerve root, is very unusual. Though unusal, this possible motility should be kept in mind during surgery for cauda equina tumors. Authors report a case of a mobile neurilemmoma of the cauda equina which was successfully removed, and discuss the pathogenesis of mobile meurilemmoma.

The authors report a case of intradural myxopapillary ependymoma of the cauda equina that was clinically similary to herniated lumbar disc disease. The tumor was totally removed under microsurgical condition and the diagnosis was confirmed pathologically.

Redundant Nerve Roots (RNRs) is an uncommon clinical condition characterized by a tortuous, serpentine, large and elongated nerve root of the cauda equina. To our knowledge, most cases of RNRs are associated with lumbar stenosis, and RNRs associated with lumbar disc herniation has not been reported until now. Here we present a rare case of unusual RNRs associated with lumbar disc herniation mimicking intradural disc herniation.

Authors experienced intra-root cavernous angioma which is very rare case among cavernous angiomas of cauda equina. Our intra-root cavernous angioma was confirmed by findings from operating field and microscopic examination. We report this case with review of the literature.

OBJECTIVE: The authors evaluate results of transfacet pedicle sparing approach for high lumbar disc herniation to avoid injury of nerve roots and the cauda equina. METHODS: Seven patients treated by transfacet pedicle sparing approach for high lumbar disc herniation were reviewed. Some thoracolumbar kyphotic patients on whom posterior procedures underwent additional posterior lumbar interbody fusion and posterolateral fusion using the mesh cage and spinal instrumentation. RESULTS: Clinical symptoms improved in all seven patients. Rigid spinal stability and correction of thoracolumbar kyphosis could be performed by the spinal instrumentation methods. CONCLUSION: The advantages of the transfacet pedicle sparing approach are less invasive, easy decompression the nerve root directly and avoidance of the risk of injury to the cauda equina while the dura is being retracted. Additionally, thoracolumbar kyphosis could be corrected. Transfacet pedicle sparing approach is an useful procedure in the surgical treatment of high lumbar disc herniation.
