Abstract
Posterior migration of a sequestered disc fragment to the posterior epidural space is extremely rare due to the natural anatomical barriers of the thecal sac. Only cases were reported in the literature. It often causes severe neurological impairment, such as cauda equine syndrome. Accurate diagnosis is difficult because magnetic resonance images may mimic those of other more common posterior epidural mass lesions. We reported two cases of posterior epidural migration of sequestered discs. Both two patients responded well to operation with complete relief of symptoms.
