Serpentine cauda equina nerve roots

A W Duncan, D K Kido

    Radiology

    Summary
    This summary is machine-generated.

    Redundant nerve roots can cause serpentine filling defects, leading to subarachnoid space obstruction. Myelography effectively demonstrated these defects in patients with extradural lesions.

    Area of Science:

    • Neurology
    • Radiology
    • Spinal Imaging

    Background:

    • Spinal stenosis and obstruction can arise from various causes, impacting neurological function.
    • Accurate diagnostic imaging is crucial for identifying the extent and nature of spinal canal compromise.

    Observation:

    • Three patients presented with myelographic findings of serpentine filling defects.
    • These defects were attributed to redundant nerve roots within the spinal canal.

    Findings:

    • Myelography using nonionic, water-soluble contrast material clearly visualized serpentine filling defects.
    • The defects resulted in total obstruction or severe stenosis of the subarachnoid space.

    Implications:

    • This study highlights redundant nerve roots as a potential cause of spinal canal obstruction.
  • Myelography is a valuable tool for diagnosing this specific etiology of subarachnoid space compromise.
