脊髓的“银杏叶征”,一文读懂

2023-05-27 新乡医学影像 新乡医学影像 发表于上海

我们今天学习一个影像征象—银杏叶征

髓外硬膜下肿瘤占成人椎管内肿瘤的80%,脊膜瘤和神经鞘瘤是常见的髓外硬膜内肿瘤,当临床遇到髓外硬膜内占位时,鉴别诊断总是绕不开这两个疾病,MRI上如何鉴别诊断?

我们今天学习一个影像征象—银杏叶征

上图为一位74岁女性患者的MR图像,我们可以看到典型的“银杏叶征”。

矢状位T1WI增强扫描示病灶位于在C5-6节段压迫脊髓。

T1WI轴位增强扫描示肿瘤移行于脊髓外侧,呈扇形畸形,并可见条形低信号影。

脊髓受压变形呈分叶状,并可见一条线(齿状韧带相关)残留在肿瘤内,文献报道“银杏叶征”诊断脊膜瘤的敏感性58%,特异性100%。

文献中研究病例表明影像上有银杏叶征的脊膜瘤起源于齿状韧带的腹侧。

病例2-7的轴位增强T1加权磁共振成像显示有“银杏叶征”的脊膜瘤。每个图像中的箭头表示肿瘤中与齿状韧带相关的低信号条纹影。
