Abstract：
UNASSIGNED: Metastasis of systemic neoplasms to the spine is common; however, the metastasis of primary spinal cord tumors to other regions in the body is an infrequent occurrence. A few case reports have described the metastasis of primary spinal cord tumors, and in most cases, patients were younger than 30 years of age.
UNASSIGNED: We present an illustrative case of a 47-year-old female with metastatic lesions to the lumbosacral vertebrae years after the initial diagnosis of an intradural, intramedullary spinal cord tumor (IMSCT). Although the surgical biopsy of the IMSCT was nondiagnostic, the patient was not found to have a separate primary neoplastic source, and the specimens of the metastatic lesions from the lumbar vertebral body were of glial origin.
UNASSIGNED: Metastasis from primary IMSCTs is extremely rare. Distant vertebral body and intracranial metastasis are even rarer yet possible. The clinical course is highly aggressive and responds poorly to current standard treatment.

摘要：
■全身性肿瘤向脊柱转移是常见的；然而，原发性脊髓肿瘤向身体其他区域的转移很少发生。一些病例报告描述了原发性脊髓肿瘤的转移，在大多数情况下,患者年龄小于30岁.
■我们介绍了一例47岁女性，在最初诊断为硬膜内数年后，腰骶椎有转移性病变，脊髓髓内肿瘤（IMSCT）。虽然IMSCT的手术活检是非诊断性的，没有发现患者有单独的原发性肿瘤来源，腰椎椎体转移性病变标本为胶质来源。
■原发性IMSCT的转移极为罕见。远处的椎体和颅内转移甚至更罕见。临床过程是高度积极的，对目前的标准治疗反应不佳。
