The Cervical Sequestrated Disc Fragment Presenting as Mass Lesion: Case Report and Review of the Literature

Case Presentation: We reviewed a rare case of the cervical sequestrated disc herniation mimicking a spinal canal extradural abscess. The 55-year-old man presented cervical axial and radicular pain. Cervical spine MRI showed an extra-axial longitudinal mass behind C5 and C6 vertebral body association with anterior compression on cord. In T2 images of lesion, the signal intensity varied from isointense to hyperintense and marked peripheral enhancement with GD injection. After unilateral right C6 hemilaminectomy, a sequestrated disc fragment was resected from epidural space.
