摘要
目的:探讨脑膜转移瘤(MC)的MRI特征,及其瘤周水肿与血管内皮生长因子(VEGF)表达的相关关系。方法采用1.5 T磁共振仪平扫加增强观察48例MC 的MRI表现,对手术切除的瘤组织行VEGF免疫组化测定。结果48例MC患者的MRI特征表现为3型,瘤组织VEGF表达越强,瘤周水肿越重(χ2=33.34,P<0.01)。结论 MC的临床诊断中,MRI扫描不可或缺;其VEGF的表达和瘤周水肿产生呈正相关关系。
Objective To discuss the MRI feature of meningeal metastasis and correlation of peritumoral brain edema and vascular endothelial growth factor(VEGF)expression.Methods 48 patients with meningeal metas-tasis were observed with plain and enhanced 1 .5 T magnetic resonance imaging scans,surgical removal of the tumor tissues was measured with VEGF immunohistochemistry.Results The patients with MC showed three types MRI fea-ture.The more vascular endothelial growth factor of the tumor tissues expressed,the more peritumoral brain edema (χ2 =33.34,P〈0.01 ).Conclusion MRI scanning is necessary for clinical diagnosis in MC.There are positive correlation between the expression of vascular endothelial growth factor of the tumor tissues and peritumoral brain edema(P〈0.01).
