摘要:
[目的]探讨由WHO Ⅰ型脑膜瘤引起的不同类型瘤旁脑水肿(peritumoral brain edema,PBE)的MR表现与脑膜瘤病理类型的关系。[方法]脑凸面及镰旁WHO Ⅰ型脑膜瘤83例,均行MR和MR增强扫描,分析脑膜瘤病理类型与PBE的MR表现的关系。[结果]脑膜瘤的不同亚型PBE 有不同的MR表现;脑膜瘤增强表现与PBE关系密切,无脑水肿与广泛脑水肿肿瘤亚型的极显著强化比例分别为66.35%与100.00% 。本组不同亚型脑膜瘤的PBE易发次序为:分泌型、血管瘤型、微囊型、过渡型(混合型)、上皮型、砂粒体型和纤维型;易发广泛PBE的亚型依次为:分泌型、微囊型、血管瘤型、过渡型、上皮型。[结论]PBE的MR表现与脑膜瘤病理亚型关系密切。

Abstract:
To explore the relationship between the MR manifestations of peritumoral brain edema (PBE) caused by WHO Ⅰ meningioma and their pathological types.[Methods]The study conducted a retrospective analysis of the clinical, pathological data of 83 cases of cerebral convexity and the falx WHO Ⅰ meningioma which all were undergone MR and enhancement scanning, and the relationship between the MR findings of PBE and the pathological types of meningiomas was analyzed.[Results]The study showed that different subtypes of meningiomas had different MR of PBE findings. Enhanced manifestations were closely related to the PBE, and the rates of very significant enhancement were 66.35% and 100.00% in the extensive PBE and without. The order prone to PBE meningioma as the following: secretory, hemangioma, microcystic, transitional (mixed), epithelial, psammomatous and fibrous type; the order prone to extensive pathological subtypes of brain edema was as follows: secretory, microcystic, hemangioma, transitional and epithelial type.[Conclusion]The possible conclusion of this study is that MR manifestations of PBE are indispensible with the pathological types of meningiomas.
