Although very rare, cases of cauda equina tumours migrating several levels have been known to occur. We report two cases of cauda equina schwannomas which migrated from its primary site, one caudally and the other one rostrally as confirmed by magnetic resonance imaging perioperatively. The first patient was a 27-year-old man and the second a 41-year-old man; both presented with back pain. This report aims to remind clinicians that certain tumours attached to the roots in the lumbar spinal canal may migrate.
