Intradural lumbar disc herniation is a rare complication of disc disease. The reason for the tearing of the dura matter by a herniated disc is not clearly known. Intradural disc herniations usually occur at the disc levels and are often seen at L4-L5 level but have also been reported at other intervertebral disc levels. ⋯ An intradural disc fragment was found and completely removed. The patient recovered fully in 3 months. Intradural lumbar disc herniation must be considered in the differential diagnosis of mass lesions in the spinal canal.
