Post-traumatic syringomyelia following uncomplicated spinal fracture.

Two cases of post-traumatic syringomyelia presenting 10 and 41 years after spinal injuries that had caused lumbar vertebral fractures but no lasting neurological deficits are reported. In both patients the caudal end of the syrinx cavities, as shown by MRI, corresponded to the level of the previous vertebral fractures. Patients presenting with post-traumatic syringomyelia after uncomplicated spinal fracture are very rare, and the significance of the past history of spinal trauma may be overlooked.
