A 30-year-old male patient with right frontal oligodendroglioma, WHO grade II. A, B MRI axial T2W and T2-FLAIR sequences showed clear boundaries and no obvious edema around the tumor. C HE staining showed low cell density lesions and loose arrangement of cells accompanied by dense fibrous background. The cell morphology is consistent, and part of the cytoplasm is transparent. (× 200). D, E DWI and ADC images with a b value of 1000 mm2/s showed the tumor was unrestricted diffusion. F Ki-67 LI was about 4% (× 200)
