Subependymomas are benign, usually asymptomatic, intraventricular tumors, the origin of which remains controversial. Spinal cord subependymomas are rare: a literature review yields 10 previous cases which are critically appraised in this report. A case of thoracolumbar intramedullary subependymoma is reported, and the histology, ultrastructure, and pre- and postoperative management are reviewed. Awareness that subependymomas may occur as a separate entity in the spinal cord should lead to increased frequency of diagnosis and a better understanding of the biological behavior of these tumors.
室管膜下瘤是一种良性的、通常无症状的脑室内肿瘤，其起源仍存在争议。脊髓室管膜下瘤很罕见：文献综述显示此前有10例病例，本报告对这些病例进行了批判性评估。本文报告了一例胸段和腰段髓内室管膜下瘤病例，并对其组织学、超微结构以及术前和术后管理进行了综述。认识到室管膜下瘤可能作为脊髓中的一种独立病变出现，应会提高诊断频率，并更好地了解这些肿瘤的生物学行为。
