Various complications after Percutaneous epidural neuroplasty (PEN), such as mechanical catheter failure, bleeding, infection, and neurological damage, were reported. A 79 years-old male suffered from spondylodiscitis and paraspinal muscle infection without epidural space involvement after lumbar PEN. The postprocedural infection was difficult to diagnose, because the patient didn’t have common signs and symptoms of infections such as fever, malaise, redness or swelling and hot sense around wound. After 7 weeks of antibiotics treatment, the hospital discharge decision was made, because his lab values and vital sign were almost normal. Most of all, he was symptom free. Early detection of post procedural infection followed by the early administration of antibiotics should be the most important therapeutic strategy for better prognosis.
