摘要
脊索瘤（Echordosis physaliphora，EP）是一种良性脊索残余，最常见于颅底。与侵袭性脊索瘤的典型病例不同，EP 不显示 T1 增强。现在，我们介绍三例 EP 患者，他们是在疑似梅尼埃病的内淋巴水肿成像中进行延迟对比增强三维 FLAIR 检查时发现的。所有 EP 病例的脊索残余均表现为强烈的延迟 FLAIR 增强。这一关于EP中FLAIR增强的新观察结果具有三重意义：（1）它可能会提高EP的检出率；（2）EP中的FLAIR增强不应被误认为是脊索瘤中的T1增强；（3）它可能会为未来旨在更好地区分EP和脊索瘤的成像研究打开一扇新窗口。
Delayed FLAIR-enhancement of benign notochordal remnant (ecchordosis physaliphora).
Ecchordosis physaliphora (EP) is a benign notochordal remnant most commonly encountered in the skull base. In opposition to typical cases of its invasive counterpart, that is, chordoma, EP does not show T1-enhancement. Now, we describe three patients with EP, discovered on delayed contrast-enhanced 3D FLAIR performed for endolymphatic hydrops imaging in suspected Menière's disease. All EP cases demonstrated intense, delayed FLAIR-enhancement of the notochordal remnant. The importance of this new observation of FLAIR-enhancement in EP is threefold: (1) it may increase the detection rate of EP, (2) FLAIR-enhancement in EP should not be mistaken for T1-enhancement in chordoma, and (3) it may open a new window for future imaging studies aiming to better differentiate EP from chordoma.
