Figure 1: (a, b) Diffusion-weighted images (b: 0,500) showing increased signals in bilateral basal ganglia. (c) ADC image at the level of the basal ganglia showing increased values with central areas of decreased values. (d) T1-weighted images showing bilateral symmetrical low signal intensity in basal ganglia without signifi cant mass effect. (e, f) T2-weighted and FLAIR images showing symmetric increased signal intensity in both basal ganglia
