FIG 2. Images from the case of a 52-year-old man with a large glioblastoma.
A, Invasion of corpus callosum and of occipitotemporal white matter is recognized on fast T2-weighted spin-echo image.
B, Invasion of corpus callosum and of occipitotemporal white matter is recognized on contrast-enhanced T1-weighted spin-echo image.
C, Invasion of subinsular white matter is clearly recognized only on the perfusion-weighted echo-planar image (arrow).
D, On the diffusion-weighted image, only cystic components of tumor are clearly shown. There is no clear difference between contrast-enhancing tumor (arrowhead) and edema (arrow).
E, On the ADC map, only cystic components of tumor are clearly shown. There is no clear difference between contrast-enhancing tumor (arrowhead) and edema (arrow).
F, Histologic examination (hematoxylin and eosin; original magnification, x250) shows a medium sized extracellular space and moderate cellularity
