The cause of syringomyelia is unknown. It has been suggested that the condition is the result of a developmental anomaly. There is an association with the Arnold-Chiari malformation in which the cerebellum extends through the foramen magnum and into the first part of the cervical spinal canal.

Other deformities which are associated with syringomyelia include:

  • spina bifida
  • cervical vertebral fusion - the Klippel-Feil syndrome
  • cervical ribs
  • kyphoscoliosis
