Post-traumatic syringomyelia is a term used to describe the formation of an intramedullary cyst filled with cerebrospinal fluid (CSF) within the spinal cord (Brodbelt & Stoodley, 2003). Though uncommon, its impact can be devastating following spinal cord injury (SCI). It can be seen as early as two months after injury, or many years later (Vernon, Silver, & Symon, 1983). For example, Ko et al. (2012) reported that syringomyelia developed within 5 years after injury in 7.3% of patients.
