Lumbar disc herniation with bone erosion is rare. We report a case of a 53-year-old male with a migrated disc fragment which caused bone erosion in his L3 vertebra. On admission the patient complained of pain and hypesthesia of his left thigh anterior region. Myelography was not able to detect the presence of the migrated disc fragment. Myelo-CT, discography, disco-CT and MRI detected the migrated disc fragment which had moved in a superior direction subligamentally from the L3/L4 disc. We did a partial laminectory and removed the migrated disc fragment and postoperatively the patient was free from pain.
