Myxopapillary ependymomas (MPEs) are rare spinal cord tumors with low rates of metastasis outside of the neuraxis. Gross total resection of MPEs can significantly improve progression-free survival; however, adjunctive treatment remains unstandardized. A 29-year-old female with a history of spina bifida occulta surgical correction and lower back pain presented with dyspnea and tachycardia. A large pulmonary artery mass was discovered consistent with pulmonary thromboembolism. It was subsequently determined to be an intravascular metastasis secondary to sacral MPE. Standardization of MPE treatment and clinical suspicion of spinal neoplasm in the setting of chronic back pain with undetermined origin are of value.
黏液乳头型室管膜瘤（MPEs）是罕见的脊髓肿瘤，在神经轴以外转移率较低。MPEs的全切除可显著提高无进展生存期；然而，辅助治疗仍未标准化。一名29岁女性，有隐性脊柱裂手术矫正史和下背部疼痛，出现呼吸困难和心动过速。发现一个大的肺动脉肿块，符合肺血栓栓塞。随后确定为继发于骶骨MPE的血管内转移。MPE治疗的标准化以及在慢性背痛病因不明的情况下对脊柱肿瘤的临床怀疑具有重要意义。
