Migration of sequestrated part to posterior epidural region in lumbar disc herniation
Abstract
Lumbar disc herniation
occurs with the emergence of the nucleus pulposus from weakened annulus
fibrosus fibers. 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.
