Abstract: A patient with a mobile schwannoma of the cauda equina is described. There was considerable discrepancy between the localization of the tumor at myelography and the findings at both initial surgery and repeat myelography, confirmed by definitive surgery. Such mobility is rare, but should be kept in mind when surgery is performed for a tumor of the cauda equina.
