Artifactual midline cervical defect seen during myelography

J J Krupka, C M D'Angelo

    Spine
    |September 1, 1978
    PubMed
    Summary

    A rare ventral extradural cervical defect occurred after myelography, mimicking a herniated disc. This previously undocumented cervical complication highlights potential imaging-related complications.

    Area of Science:

    • Neurosurgery
    • Radiology
    • Diagnostic Imaging

    Background:

    • Myelography is an invasive diagnostic procedure used to visualize the spinal cord and nerve roots.
    • Extradural defects are typically associated with conditions like disc herniation or tumors.
    • Previous reports of myelography-induced extradural defects have been limited to the lumbar spine.

    Observation:

    • A case presented with a ventral extradural cervical defect.
    • The defect was identified following contrast medium extension during the myelography procedure.
    • The imaging appearance closely simulated a cervical disc herniation.

    Findings:

    • The cervical extradural defect is a novel finding, distinct from previously described lumbar occurrences.
    • The etiology of this defect is attributed to the extension of contrast material during myelography.
    • This phenomenon represents a potential iatrogenic complication of the diagnostic procedure.

    Implications:

    • Clinicians should be aware of this potential complication during cervical myelography.
    • Differential diagnosis for cervical disc herniation should include imaging artifacts.
    • Further investigation into the precise mechanisms and prevention strategies is warranted.
