[Intradural lumbar disk hernias. Apropos of 6 cases and review of the literature].
Transdural discal hernia is a rare complication of lumbar discal pathology. In this paper, we report five cases of transdural herniated disc and one intraradicular discal hernia. In the literature review, we found 97 cases since the first case described by Walter Dandy in 1942. The main risk in this exceptional location of discal hernia is to miss an intradural discal piece leading to a poor result. MRI or CT scan with intrathecal contrast can show an intradural lesion but they usually fail to indicate its precise nature.
