Methicillin-resistant Staphylococcus aureus epidural abscess after transforaminal epidural steroid injection.

Transforaminal epidural steroid injections are provided frequently for patients with lumbar radiculopathy, having demonstrated efficacy and safety. We present a patient who developed methicillin-resistant Staphylococcus aureus epidural abscess 11 days after a transforaminal epidural steroid injection. The abscess required surgical intervention and intravenous vancomycin. Fortunately, the patient made a full recovery, and continues to do well one year later. The incidence, etiology and treatment of epidural injection-related infections are reviewed.
