Non-discogenic sciatica can be caused by any lesion along the course of the lumbosacral nerve roots and sciatic nerve. We aim to present a rare case of refractory sciatica in an otherwise healthy 25-year-old man. He complained of left leg pain without significant back pain. Extensor hallucis longus muscle was weak on the left side with limited straight leg rising. On magnetic resonance imaging, a space-occupying lesion resembling a sequestrated disc was noted that after surgical decompression, epidural varicosis was demonstrated.
