Transdural lumbar disk herniation, where a disc fragment migrates through the dura, causes severe symptoms. Imaging revealed enhanced intradural disc material, suggesting vascularization in this rare condition.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Radiology

Background:

  • Transdural migration of intervertebral disc fragments is a rare condition.
  • It is associated with more severe clinical manifestations compared to extradural herniation.
  • This condition requires careful diagnostic evaluation and surgical consideration.

Observation:

  • The study reports on two patients with transdural lumbar disc herniation without prior surgery.
  • Magnetic resonance imaging (MRI) showed intense enhancement of the intradural disc material in both cases.
  • Pathological examination of one specimen revealed vascularization of the intradural fibrocartilage.

Findings:

  • Intradural disc material demonstrates intense enhancement on MRI, indicating potential vascularization.

Related Experiment Videos

  • Vascularization of intradural fibrocartilage may be a characteristic feature of transdural disc herniation.
  • This finding aids in differentiating transdural from extradural disc herniations.

    • Implications:

    • Enhanced MRI visualization of intradural disc fragments can improve diagnostic accuracy.
    • Understanding the vascular nature of intradural disc material may influence surgical approaches.
    • This case report contributes to the limited literature on transdural lumbar disc herniation.
