Case report: In this article, we describe the case of a 40 years-old woman who had a previously implanted fourth ventricle to spinal subarachnoid space shunt for the treatment of syringomyelia in a context of Chiari syndrome. The catheter migrated intradurally to the lumbosacral space, but in the absence of neurological repercussions, we decided to leave it in place. Conclusions: To the best of our knowledge this is the first case described in the literature of a catheter migration in the subarachnoid space from occipito-cervical to lumbo-sacral level.
