Summary:Background: Mobile schwannomas of the cauda equina are rare. Preoperative planning should take into consideration the possibility of tumor migration, avoiding unnecessary additional laminectomy or second operation. Case Description: A patient with a previously known lumbar schwannoma was being managed conservatively until symptoms exacerbated and led to a new MR. When this study revealed caudal migration of the schwannoma from L3 to the L4-L5 levels, a right hemilaminectomy was performed for tumor resection. Conclusion: Great care must be taken in the surgical resection of schwannomas as they may migrate from their initial location.
