Figure 2: Images of a 35-year-old male patient. (a) T2-weighted axial magnetic resonance imaging (MRI) image showing a right medial frontal low-grade glioma arising from the short arcuate fibers in the region of the superior and middle frontal gyrus, (b) T1-weighted contrast sagittal image showing the hypointense tumor without any contrast enhancement, (c) Tractography image showing the tumor medial to the vertical group of projection fibers, (d) Functional MRI image showing the motor area abutting the posterior margin of the tumor, (e) Tractography images showing the tumor displacing the vertical group of projection fibers laterally and the medial SLF inferiorly, (f) Postoperative T1-weighted contrast-enhanced image showing the resection cavity, (g) Postoperative T2-weighted axial image showing the resection cavity, (h) Postoperative fluid-attenuated inversion recovery (FLAIR) image showing the tumor resection, and (i) Postoperative specimen showing the en masse resection
