Intradural disc herniation is a rare phenomenon in spine surgery. Diagnosis is difficult despite current neuroradiologic imaging techniques.
We present a case of a 59-year-old man with lumbar and radicular pain and a recurrent lumbar herniation. A laminectomy was performed after no clear disc herniation in the epidural space was found and an intradural mass was palpable. A durotomy showed an intradural disc fragment that was removed, followed by an arthrodesis.
Only intraoperative findings lead to a definitive diagnosis for intradural herniation. A durotomy needs to be performed. In this case, an arthrodesis was necessary to avoid complications of segmental instability.
