[Characteristics of the white matter involvement sites on MRI in patients with multiple gliomas].

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
