Two completely intradural extraosseous tumors with the histologic appearance of chordoma or ecchordosis physaliphora caused symptoms and, in 1 case, ultimately the death of a 44-year-old man. The literature contains 5 similar cases, 2 of which were associated with intratumoral and subarachnoid hemorrhage. In view of the circumscribed nature of such tumors and their lack of osseous involvement, they lend themselves to surgical resection. These features may justify distinguishing "intradural chordoma" from classic chordoma.
两例具有脊索瘤或泡状脊索样畸形组织学表现的完全硬膜内骨外肿瘤引起了症状，其中1例最终导致一名44岁男性死亡。文献中包含5例类似病例，其中2例与肿瘤内及蛛网膜下腔出血有关。鉴于此类肿瘤的局限性及其无骨质受累情况，它们适合手术切除。这些特征可能证明将“硬膜内脊索瘤”与经典脊索瘤区分开来是合理的。
