Acknowledgement: This study was supported by a grant from the Wooridul Spine Foundation. Patients with lumbar disc herniation can present with contralateral symptoms, which sometimes confuse the surgeons of making a surgical plan. We report a patient with recurrent lumbar disc herniation on the left side at the L4-5 level, who presented with leg pain on the right side. We performed percutanoues endoscopic lumbar discectomy from the herniation side and the patient showed improvement of leg pain immediately after the procedure.
