Posterior and anterior epidural and intradural migration of the sequestered intervertebral disc: Three cases and review of the literature.

Conclusion/clinical relevance: Posterior and anterior epidural, and intradural disc migration may manifest with clinical symptoms indistinguishable from those associated with non-sequestered lumbar disc hernias. Missed, migrated disc fragments can be implicated as a cause of low back pain, radiculopathy or cauda equina syndrome, especially in the absence of visible disc herniation. A high index of suspicion needs to be maintained in those cases with unexplained and persistent symptoms and/or no obvious disc herniation on MR images.
