经常并发于脑膜瘤的脑水肿是使病人病残和致死的潜在原因.此水肿发生的原因尚不清楚,以往的研究曾提出在小型脑膜瘤中,脑水肿的发生与肿瘤的有丝分裂数目,血管供应情况,组成细胞数量等有关联,而与脑膜瘤的大小、部位和组织学类型无关. Brain edema, often associated with meningiomas, is a potential cause of morbidity and mortality in patients and the etiology of this etiology is unclear. Previous studies have suggested that in small meningiomas, the occurrence of cerebral edema is related to the number of mitotic tumors, Supply, composition of the number of cells and other related, but not with meningioma size, location and histological type.
