Magnetic resonance images (MRI) of migrated nucleus pulposus after collagenase treatment of lumbar disc herniation are rarely published. Here, we describe a 65-year-old woman with L5-S1 intervertebral disc herniation on the rear left. The patient was treated with a lumbar disc collagenase injection, and the pain was relieved. Two weeks later, the patient suddenly developed pain again after engaging in weight-bearing activity. Lumbar MRI showed a nodule in the spinal canal at the L5-S1 level. The patient underwent surgical treatment two days later. Pathology showed that the nodule was nucleus pulposus tissue. It is important to understanding the MR manifestations of migrated nucleus pulposus after collagenase treatment to prevent such misdiagnosis.
胶原酶治疗腰椎间盘突出症后髓核迁移的磁共振成像（MRI）报道很少。在此，我们描述一位65岁女性，其左后方存在L5-S1椎间盘突出症。该患者接受了腰椎间盘胶原酶注射治疗，疼痛得到缓解。两周后，患者在进行负重活动后突然再次出现疼痛。腰椎MRI显示L5-S1水平椎管内有一个结节。两天后患者接受了手术治疗。病理显示该结节为髓核组织。了解胶原酶治疗后髓核迁移的磁共振表现对于预防此类误诊很重要。
