Conus Medullaris Syndrome Days After A Single Epidural Steroid Injection

Abstract

Background: Epidural steroid injections (ESI) are commonly used in treatment of chronic lower back pain. Conus medullaris and cauda equina syndromes are rare complications of ESI. However, these typically occur after multiple injections within a few minutes to hours. Some reported cases are also transient, with patients completely regaining neurological function. We discuss a unique case of a patient developing conus medullaris syndrome over 24 hours after a single epidural steroid injection without resolution of symptoms.
