Abstract： 目的研究颅内血管外皮细胞瘤的MR影像表现,并与脑膜瘤进行对比分析.方法选取经手术及病理证实的颅内血管外皮细胞瘤27例和脑膜瘤236例.对2组肿瘤的MR及临床观察指标进行单因素和多因素分析,统计学方法包括χ2检验、秩和检验和Logistic回归.结果患者性别(χ2=6.981)、肿瘤形态(χ2=39.949)、肿瘤内血管流空信号(χ2=12.366)、肿瘤内坏死与囊变信号(χ2=37.432)、肿瘤附着硬膜的类型(广基底或窄基底)(χ2=16.956)、T1WI信号强度(χ2=14.880)、T2WI信号强度(χ2=37.068)、肿瘤增强程度(χ2=10.081)、肿瘤增强均匀性(χ2=17.014)等因素在血管外皮细胞瘤组与脑膜瘤组之间差异具有非常显著性意义,P值均<0.01;"硬膜尾征" (χ2=5.655)在两组之间差异具有显著性意义,P<0.05.患者初次就诊时年龄在两组间差异具有显著性意义(双侧检验P=0.015),P<0.05;患者的病程在两组间差异具有非常显著性意义(双侧检验P=0.013),P<0.05.Logistic回归方程中,变量"肿瘤形态"P<0.01;变量"T2WI信号强度"和变量"硬膜尾征"P<0.05.结论在颅内血管外皮细胞瘤与脑膜瘤的MR影像鉴别诊断诸多因素中,肿瘤呈分叶状、T2WI呈等高混杂信号影,以及缺少"硬膜尾征"对诊断血管外皮细胞瘤最有意义,结合其他因素的分析有助于提高颅内血管外皮细胞瘤的MR影像诊断水平.
