A Case of the Redundant Nerve Root Syndrome Mimicking Intradural Spinal Tumor

The redundant nerve root syndrome is not common and demonstrates a large, elongated, and tortuous nerve roots of cauda equina. Usually, the diagnosis of this syndrome is not difficult with the radiological finding and clinical symptom. The authors report a case of the redundant nerve root syndrome mimicking intradural spinal tumor in view of the symptom and radiological findings. Magnetic resonance imaging revealed a globular intradural mass just above canal stenosis. Decompressive laminectomy and durotomy improved back pain and radicular pain. From the experience of this case, the relief of nerve root compression is recommended as early as possible in the redundant nerve root syndrome.
