Intradural disc herniation has been reported as a rare and particular type of intervertebral disc herniation. It occurs mostly in the lumbar spine, and rarely in the cervical or thoracic spine. Non-traumatic cervical intradural disc herniation is rare, with only 17 cases reported in English literature at the cervical region and can manifest itself by severe symptoms such as Brown-Sequard syndrome, transverse myelopathy and radiculopathy. We present a unique case of intradural cervical disc herniation only causing lower extremity monoplegia. To our knowledge, this is the first case described in the literature. The patient underwent microsurgical removal of the herniated disc via an anterior approach followed by interbody fixation using a cervical cage.
