Percutaneous epidural neuroplasty (PEN) is one of the most widely used alternatives for treating lumbar spinal stenosis (LSS). PEN may be a good option, if conservative treatments such as medical treatment, epidural steroid injection, or physical therapy fails to relieve patients’ symptoms. Especially, PEN using balloon catheter can improve patients’ outcome more successfully through the dilation of stenotic area and the lysis of epidural adhesion. Although PEN is a relatively safe procedure, several complications including transient pain aggravation, dural puncture, subdural, intradiscal, and intravasucular injection have been reported. In this case report, the authors share our encounter with a rare complication of intervertebral disc herniation following PEN using balloon catheter.
