A 16-year-old girl patient with a WHO grade IV glioma; images show a large mass of non-homogeneous signal intensity in the left thalamic and deep periventricular white matter (asterisk). It displays low SI on axial T1WI (A), high SI on axial FLAIR image (B). It is seen crossing midline with associated high T2SI edema and mass effect in coronal T2-weighted image (C). It shows restricted diffusion (black arrows) in the form of high SI on DWI (b1000 image) and low SI on ADC grayscale map (E, D). High perfusion of the mass (white arrows) is seen in axial ASL grayscale and color CBF maps (F, G)
