We report two cases in which the MRI appearances mimicked the dural tail sign; a glioma extending into the subarachnoid space, and a meningioma extending to the subdural space. They indicate that tumour invasion into the subarachnoid or subdural space, should be considered when prominent linear enhancement is observed along the dura mater adjacent to tumours.
我们报告了两例MRI表现类似硬膜尾征的病例；一例为延伸至蛛网膜下腔的胶质瘤，另一例为延伸至硬膜下腔的脑膜瘤。这表明，当在肿瘤附近的硬脑膜处观察到明显的线性强化时，应考虑肿瘤侵犯蛛网膜下腔或硬膜下腔。
