Brown-Sequard Syndrome After Radiofrequency Therapy of the Left C3 Medial Branch

Abstract

<p>A 59-year-old woman presented with a 5-year history of neck pain and intractable headache radiating from the occipital region to the supra-orbital region. Magnetic resonance imaging demonstrated a C5–6 herniated intervertebral disc and bulging disc at C4–5. Left C3 medial branch radiofrequency neurotomy was performed. Although the procedure was uneventful, the patient developed a cervical spinal cord haemorrhage that caused Brown–Séquard syndrome. The haemorrhage was presumably caused by iatrogenic injury of a radicular artery during the procedure.</p> <p> </p>
