Serpentine lumbar nerve roots

D H Carlson

    Journal of the Canadian Association of Radiologists
    |June 1, 1982

    Summary
    This summary is machine-generated.

    Serpentine nerve roots, identified in myelograms, indicate spinal canal obstruction. These findings suggest a link between nerve root stretching and spinal blockages, requiring careful differentiation from other lesions.

    Area of Science:

    • Radiology
    • Neurosurgery
    • Spinal Imaging

    Background:

    • Myelography is a key diagnostic tool for spinal canal evaluation.
    • Understanding nerve root morphology is crucial for diagnosing spinal pathologies.
    • Previous studies have not extensively detailed serpentine nerve roots in relation to spinal obstruction.

    Observation:

    • Serpentine nerve roots were observed in 15 out of 110 myelograms (13.6%).
    • These specific nerve root formations were associated with near-block conditions in the spinal canal.
    • The study identified six patients exhibiting these serpentine nerve roots.

    Findings:

    • A degree of spinal canal obstruction appears necessary for the formation of serpentine nerve roots.
    • Intermittent stretching of nerve roots over spinal spurs contributes to their development.

  • Serpentine roots represent a distinct radiological finding, not to be confused with arteriovenous malformations or other lesions.

    • Implications:

    • Serpentine nerve roots may be a relatively common finding in cases of significant spinal block.
    • Accurate identification of serpentine roots aids in diagnosing the severity and nature of spinal canal obstruction.
    • This observation highlights the importance of detailed myelographic analysis for spinal nerve root pathology.
