1 A 22-year-old man with posterior left frontal grade 2 astrocytoma.
A 22-year-old man with posterior left frontal grade 2 astrocytoma. A, Axial 3D inversion recovery fast-spoiled gradient-echo T1-weighted image shows the tumor centered along the anterior aspect of the precentral gyrus. The white gray sign is still noticeable as decreased contrast of the gray-white interface along the central sulcus (arrows). This is also appreciable on the contralateral normal side. B, Functional data with hand-motor tasks (light blue = right hand, yellow = left hand) confirm the location of the primary motor and somatosensory cortices. O.F. Kaneko et al.
