High grade extraventricular supratentorial ependymoma’s in adults are uncommon neoplasms with imaging features that can mimic cortical tumors if small and high-grade gliomas (HGG) if large. No previous work has tried to discriminate ependymoma from high grade gliomas using MRI. Our work evaluates preoperative diffusion weighted imaging for discrimination of ependymomas from grade III and grade IV gliomas using textural analysis. Results demonstrate significant differences in the histogram and first order textural features derived from diffusion weighted imaging in cases of ependymomas and high-grade gliomas.
