Lumbar intradural arachnoid diverticulum with cauda equina compression

B J Zumpano, R L Saunders

    Surgical Neurology

    Summary

    An intradural lumbar arachnoid diverticulum, a rare spinal lesion, caused severe symptoms due to cauda equina compression. Inadvertent drainage relieved the debilitating pain, highlighting a diagnostic approach for this unusual condition.

    Area of Science:

    • Neurosurgery
    • Spinal Imaging
    • Neurology

    Background:

    • Intradural lumbar arachnoid diverticula are exceptionally rare spinal lesions.
    • Literature review reveals only one prior reported case of such an intradural lesion.

    Observation:

    • A case presented with an intradural lumbar arachnoid diverticulum causing mild cauda equina compression.
    • Symptoms included debilitating back and radicular pain, and sensory disturbances, particularly when upright or bending forward.

    Findings:

    • Symptoms were alleviated by inadvertent drainage of the diverticulum.
    • Percussion tenderness over the diverticulum level was a consistent clinical finding.
    • Supine myelography is identified as the key diagnostic method.

    Implications:

    • This case underscores the rarity and diagnostic challenges of intradural lumbar arachnoid diverticula.
    • Effective symptom relief can be achieved through drainage, suggesting a potential treatment pathway.
    • Highlights the importance of supine myelography in diagnosing these rare spinal conditions.
