Introduction: Intradural disc herniation is a rare disease and it accounts for 0.26-0.30% of all herniated discs. Little was known about intradural disc herniation in the previous studies.
Case report: Here, we report a 49-year-old male patient with Brown-Sequard syndrome caused by spontaneous cervical intradural disc herniation at C6-C7 level.
Conclusions: It is difficult to be diagnosed before the surgery through computed tomography scans, myelograms, and magnetic resonance image scans. Once it was diagnosed, an operation should be performed.
