The term ecchordosis physaliphora (EP) has been used historically to describe a benign notochordal remnant with no growth potential, most commonly occuring in the central clivus. Unfortunately, the radiologic appearance of EP overlaps considerably with the appearance of low-grade chordomas, which do have the potential for growth. In this article, we review new pathologic terminology that better describes this family of diseases, and we propose new radiologic terms that better address the uncertainty of the radiologic diagnosis. The surgical importance of accurate terminology and the implications for patient care are discussed.
历史上，术语“脊索瘤样 physaliphora 瘤（EP）”用于描述一种无生长潜能的良性脊索残余物，最常见于颅底正中斜坡。不幸的是，EP 的影像学表现与低度 chordomas 重叠很大，后者确实有生长的潜力。在本文中，我们回顾了更好地描述这组疾病的新病理术语，并提出了更好地解决影像学诊断不确定性的新影像学术语。讨论了准确术语的手术重要性及其对患者护理的影响。
