FIG 4. Anaplastic oligodendroglioma in a 59-year-old man.
A, Axial T2-weighted (3986/99) fast SE image shows a high-signal-intensity mass in the right temporal and frontal lobes.
B, Axial T1-weighted (600/14) image shows that the mass is isointense to slightly hyperintense.
C, Axial contrast-enhanced T1-weighted (600/14) image shows the inhomogeneous and partial tumor contrast enhancement with a CER up to 62.52. There are nodular-like enhancement areas within the tumor.
D, Photomicrograph of the specimen (hematoxylin-eosin stain; original magnification, x100) shows an area with high cellularity and increased neovascularity.
