A dural tail, which is a linear enhancement along the dura mater on contrast T1-weighted resonance images, is considered as a common and useful sign for distinguishing meningioma from other intracranial lesions. However, the specific nature of dura tail signs is still controversial. To the best of our knowledge, only seven cases of glioblastoma multiforme have been described with dural tail signs. Here, we report a case of glioblastoma multiforme with a dural tail sign and cerebrospinal fluid cleft sign and review the relevant literature.
硬脑膜尾征是指在对比增强 T1 加权磁共振成像上沿着硬脑膜走行的线性强化，被认为是鉴别脑膜瘤与其他颅内病变的一种常见且有用的征象。然而，硬脑膜尾征的特异性仍然存在争议。据我们所知，仅有 7 例多形性胶质母细胞瘤伴有硬脑膜尾征的病例被描述。在此，我们报告了一例伴有硬脑膜尾征和脑脊液裂隙征的多形性胶质母细胞瘤，并复习了相关文献。
