The posterior epidural migration of sequestered lumbar disc fragments is an uncommon event. The authors report two such cases in which patients presented with either intense radicular pain or cauda equina syndrome. The radiological characteristics were the posterior epidural location and the ring enhancement of the mass after injection of contrast material. The major diagnostic pitfalls are discussed.
