Deskripsi
Migration of disc fragment into the dorsal epidural space is a rare phenomenon. It happens when a sequestrated disc fragment transgresses the anatomical barriers to reach dorsal to the dural sheath. We describe a rare situation where a dorsally migrated, sequestrated disc fragment also had a partial intradural extension. The case is highlighted for the extreme rarity of such presentation, role of magnetic resonance imaging scan on the preoperative diagnosis and crucial surgical principles.
