We present a man in his 60s with a dorsal thoracic arachnoid web spanning levels T6-T8. The patient presented with gait abnormalities, severe neuropathic lower back pain and mild urinary incontinence without sensory deficits. He underwent laminectomy with arachnoid web fenestration. At the 6-week postoperative follow-up appointment, he had increased muscle strength in his lower extremities and was able to walk without shuffling his feet, with a straight back and standing upright. This is a marked improvement from his previous hunched and shuffling gait. He has had partial resolution of his neuropathic low back pain. Arachnoid webs are often confused with other neurological disorders, most commonly idiopathic ventral cord herniation, which prolongs the time to surgical intervention. Eventual fenestration of our patient's web led to significant improvement in gait and partial relief of his neuropathic low back pain.
