Lumbar disc herniation can be seen as protruding, extruded and sequestered type. Sequestered parts often replace to superior, inferior and laterally. Migration of disc fragment to the posterior epidural space is extremely rare. Here, two cases with posterior epidural migration were reported. One patient had radicular symptom and other one had cauda equina syndrome. In the lumbar magnetic resonance imaging of the patients, there was a mass at the posterior epidural space, compressing the dural sac. The patients underwent emergency operation and the lesions at the epidural space were proved to be sequestered disc fragments which migrated to posterior epidural space. Clinical symptoms of the patients were improved after surgery and the patients were discharged with full recovery.turinfo:eu-repo/semantics/openAccessLumbar disc herniationSequestered discarticle413741000404541200010
