Clinical Significance of Epidurography Contrast Patterns after Adhesiolysis during Lumbar Percutaneous Epidural Neuroplasty

<div>Representative case of a 60-year-old man with radicular pain in the left leg who underwent lumbar PEN. (a, b) Magnetic resonance imaging shows lumbar disc herniation and foraminal stenosis at the level of L4-5-S1 (asterisks). (c) The first epidurogram shows a filling defect at the left L5-S1 foramen. The catheter is inserted to the stenotic foramen, and mechanical adhesiolysis is attempted. (d) The final postadhesiolysis epidurogram shows excellent extraforaminal contrast spread. The patient exhibited significant pain relief and functional recovery after PEN. PEN: percutaneous epidural neuroplasty.</div>
