A "dural tail" on Gd-DTPA-enhanced MRI has been often observed adjacent to meningiomas and considered to be useful in distinguishing meningioma of the cerebellopontine angle from acoustic neuroma. However, demonstration of a dural tail adjacent to an acoustic neuroma indicates that this sign is not specific.
在钆喷酸葡胺增强磁共振成像（Gd-DTPA-enhanced MRI）上，常常可观察到脑膜瘤附近有“硬膜尾征”，且该征象被认为有助于鉴别桥小脑角脑膜瘤与听神经瘤。然而，听神经瘤附近出现硬膜尾征表明该征象并不具有特异性。
