"Dural tail sign" (DTS) which is a thickening of the dura adjacent to an intracranial pathology on contrast-enhanced T1 MR Images, was first thought to be pathognomonic of meningioma, however, many subsequent studies demonstrated this sign adjacent to various intra- and extra-cranial pathologies and in spinal lesions. In this paper we outline the history, accompanying pathologies and the differentiation and probable pathophysiology of DTS. We also discuss whether we can predict tumoral involvement of the dural tail before surgery and whether the dural tail adjacent to a tumor should be resected.
“硬膜尾征”(DTS)是指在对比增强T1加权磁共振成像上,颅内病变附近硬脑膜增厚,最初被认为是脑膜瘤的特征性表现,然而,随后的许多研究表明,在各种颅内和颅外病变以及脊柱病变附近均可出现此征象。在本文中,我们概述了硬膜尾征的历史、伴随的病变、鉴别诊断以及可能的病理生理学。我们还讨论了术前能否预测肿瘤对硬膜尾的侵犯,以及肿瘤附近的硬膜尾是否应予以切除。
