    Summary

    A case study reveals that redundant cauda equina nerve roots can migrate. These nerve roots, initially below spinal stenosis, moved above it on repeat imaging, appearing normal.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Radiology

    Background:

    • Spinal stenosis can cause compression of neural elements.
    • Redundant nerve roots in the cauda equina are an uncommon finding.

    Observation:

    • A patient presented with redundant cauda equina nerve roots initially observed below a spinal stenosis.
    • Serial imaging demonstrated a dynamic change in the position of these nerve roots.

    Findings:

    • The redundant cauda equina nerve roots migrated cranially, moving above the level of the spinal stenosis.
    • Post-migration, the lower nerve roots appeared normal on imaging.

    Implications:

    • This case highlights the potential mobility of redundant cauda equina nerve roots.
    • Understanding this migratory pattern may be crucial for accurate diagnosis and surgical planning in spinal stenosis cases.
