Abstract：
Posterior epidural migration of herniated lumbar disc fragments is a rare pathological entity. This can lead to major neurological deficits. Here, we present a rare case of sequestrated lumbar disc fragment migration into the epidural space. A 49-year-old-man presented with severe low back pain and weakness of the long extensor muscle of the hallux. MRI of the lumbar spine revealed posterior epidural lesion at the L4-L5 level. The disc fragment was isointense on T1 and T2-weighted Images (WI). The mass lesion was removed after decompressive laminectomy. Pathological investigation revealed an intervertebral disc fragment. The patient\'s condition improved postoperatively.
