BACKGROUND
Multiple myeloma (MM) has the propensity to spread to vertebral bodies; however, extramedullary plasmacytomas involving the central nervous system are extremely rare.
OBSERVATIONS
The authors report the first intradural extramedullary plasmacytoma in the lumbar region of the spine in a patient with preexisting MM. They present a 50-year-old female with severe back and radicular pain and progressive neurological deficit.
LESSONS
MM is typically treated with chemotherapy and radiation therapy. However, in this unique case, resection proved to be a key part of treatment.
背景
多发性骨髓瘤（MM）易于扩散至椎体；然而，累及中枢神经系统的髓外浆细胞瘤极为罕见。
观察结果
作者报告了首例发生于一名已有MM患者腰椎区域的硬脊膜内髓外浆细胞瘤。他们介绍了一名50岁女性，有严重的背部和神经根性疼痛以及进行性神经功能缺损。
经验教训
MM通常采用化疗和放疗进行治疗。然而，在这个独特的病例中，手术切除被证明是治疗的关键部分。
