Abstract

|
|
A 77-year-old woman presented with bilateral leg weakness, accompanied by severe axial back and radicular pain, after a L4?5 epidural injection. She had been receiving misappropriated epidural injections for the last few months. A contrast-enhanced magnetic resonance image showed rim enhancing, spinal canal compromising cystic lesion at the posterior epidural space of L4?5. During surgery, a severely central compromised non-communicating cystic lesion located at posterior epidural space was resected. A histological report of this lesion confirmed a pseudocyst containing a degenerated synovial tissue. Herein, we report our experience of cauda equine syndrome after epidural injection with successful treatment
