We describe a 70 year-old-patient with a rare, misleading presentation of lumbar disc prolapse, which on CT mimicked a synovial cyst. The whole nucleus pulposus had herniated, become sequestrated, and migrated behind the theca adjacent to the L4-5 facet joint. There was no continuity of the disc material with the intervertebral space. A fenestration was performed and the sequestrated disc material was found free of adhesions, and removed completely without difficulty. Histopathological examination confirmed the diagnosis. The patient had complete relief from his pain.
我们描述了一位70岁的患者，其腰椎间盘突出症的表现罕见且具有误导性，CT显示类似滑膜囊肿。整个髓核已突出、游离，并迁移至L4-5小关节相邻的硬膜囊后方。椎间盘物质与椎间隙无连续性。进行了开窗手术，发现游离的椎间盘物质无粘连，顺利完全切除。组织病理学检查确诊。患者疼痛完全缓解。
