The retrospective study included 122 cases of multiple glioma and 183 cases of single glioma. Of these, there were 74 males and 48 female with multiple gliomas, aged 18 to 83 (53±13) years, and 104 males and 79 females with single gliomas, aged 10 to 84 (51±14) years. A standard spatial-based lesion analysis method was used for constructing a spatially distributed frequency heatmap of multiple gliomas, to observe the characteristics of their white matter invasion sites. The spatial distribution was more frequent in the subventricular zone, corpus callosum and cingulate gyrus in the multiple glioma group compared to the single glioma group (P<0.001).The white matter areas of multiple gliomas were more extensively involved, with more frequent involvement of the conjoined fibers (corpus callosum, P<0.05) and contact fibers (cingulate, dome, 0.05<P<0.10) areas.The spatial distribution of the brain and the white matter invasion of multiple gliomas have certain site specificity.
本研究回顾性分析了多发脑胶质瘤122例及单发脑胶质瘤183例。多发脑胶质瘤中男74例，女48例，年龄18~83（53±13）岁；单发脑胶质瘤中男104例，女79例，年龄10~84（51±14）岁。采用基于标准空间的病灶分析方法构建多发脑胶质瘤空间分布频次热图，观察其白质受侵犯的部位特征。与单发脑胶质瘤组相比，多发脑胶质瘤组空间分布更多出现在室管膜下区、胼胝体区及扣带回（P<0.001），多发胶质瘤白质受累区更为广泛，以连合纤维（胼胝体体部，P<0.05）和联络纤维（扣带、穹隆，0.05<P<0.10）区受累频次更多。多发脑胶质瘤的大脑空间分布及白质受侵具有一定的部位特征性。.
