| 摘 要： | 目的:探讨囊性脑膜瘤的CT和MRI表现及相关临床特征,提高特殊类型脑膜瘤的认识水平。方法:回顾性分析21例分析经手术和病理证实的囊性脑膜瘤的影像学和相关临床资料。结果:囊性脑膜瘤主要发生于大脑凸面和大脑镰旁,多为实质肿块和囊腔并存,囊腔大小不等。肿瘤实质CT平扫呈等或稍高密度;T1WI为等或稍低信号,T2WI呈等或稍高信号,增强扫描均匀强化。囊壁强化多见于NautaⅢ型,"硬脑膜尾"征多见于NautaⅠ型和Ⅱ型。结论:CT和MRI能明确肿瘤实质部分和囊腔的相对位置关系有利于囊性脑膜瘤诊断并区分NautaⅡ型和Ⅲ型,囊液的MRI信号特征在一定程度上能反映其形成机制,增强MRI可对手术切除范围提供关键信息。

| Abstract: | Objective: To study the CT and MRI features of cystic meningioma in relation to its clinical manifestations.Methods: CT and MRI findings and relative clinic data of 21 cystic meningiomas proved by operation and pathology were reviewed retrospectively.Results: Most cystic meningiomas were located in cerebral convexity and falx.Substantial and cystic parts coexisted in most tumors.Substantial parts showed iso-or slightly hyper-density signals on CT plain scan,presented as iso-or slightly hypo-intensity signal... |
