Spontaneous resorption of intradural lumbar disc fragments

Background contextIntradural disc herniation is relatively rare complication of the spinal degenerative process that occurs most frequently in the lumbar part of the spine. Both myelographic and magnetic resonance features of this entity have been described, and the mechanism of intradural herniation has already been proposed and generally accepted. In this article, we present a case of spontaneous resorption of an intradural, fragmented intervertebral disc. Spontaneous resorption of intradural disc fragments has not been previously reported.PurposeTo discuss a possible mechanism of spontaneous resorption of the subdural disc fragments.Study designCase report and literature review.MethodsRadiological follow-up of a 46-year-old man with the intradural herniation of disc fragments.ConclusionThe reaction generated by the meninges might lead to the complete resorption of intrathecally localized disc fragments.
