Water-soluble contrast myelography can cause complications. Air injected into the thecal sac may mimic a lesion on myelography, requiring CT confirmation to identify this pseudolesion.

Area of Science:

  • Radiology
  • Medical Imaging
  • Neurology

Background:

  • Water-soluble contrast myelography is a diagnostic procedure.
  • Complications associated with this technique are a concern in clinical practice.

Observation:

  • Accidental air injection into the thecal sac can occur during myelography.
  • This air can create a false appearance of an extramedullary, intradural defect.

Findings:

  • The inadvertent introduction of air into the thecal sac can be misinterpreted as a pathological lesion.
  • Computed Tomography (CT) following myelography is crucial for accurate diagnosis.

Implications:

  • CT examination post-myelography is essential to differentiate true lesions from air pseudolesions.
