Spontaneous resorption of intradural lumbar disc fragments.
BACKGROUND
Intradural 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.


OBJECTIVE
To discuss a possible mechanism of spontaneous resorption of the subdural disc fragments.


METHODS
Case report and literature review.


METHODS
Radiological follow-up of a 46-year-old man with the intradural herniation of disc fragments.


CONCLUSIONS
The reaction generated by the meninges might lead to the complete resorption of intrathecally localized disc fragments.
