Recurrent symptoms after lumbar spine surgery are often due to epidural fibrosis or disc protrusion. Computed tomography (CT) with contrast is a preferred imaging method for diagnosis in failed back syndrome.

Area of Science:

  • Neurosurgery
  • Radiology
  • Orthopedics

Background:

  • Failed back syndrome is a common complication after lumbar spine surgery.
  • Differentiating between post-operative epidural fibrosis and recurrent disc protrusion is crucial for patient management.

Purpose of the Study:

  • To review the practical aspects and diagnostic accuracy of computed tomography (CT) in failed back syndrome.
  • To highlight potential pitfalls and less common abnormalities in CT imaging for this condition.

Main Methods:

  • Review of clinical practice and diagnostic imaging techniques.
  • Emphasis on computed tomography (CT) with intravenous contrast medium.
  • Comparison with myelography for diagnostic specificity.

Main Results:

  • Computed tomography (CT) is generally preferred over myelography for diagnosing recurrent symptoms post-lumbar surgery.
  • Intravenous contrast administration enhances the diagnostic specificity of CT.
  • CT can identify both epidural fibrosis and recurrent disc protrusion.

Conclusions:

  • Computed tomography (CT) is a valuable tool for evaluating failed back syndrome.
  • Understanding potential imaging pitfalls is essential for accurate diagnosis.
  • Contrast-enhanced CT improves the differentiation between epidural fibrosis and recurrent disc protrusion.
