Figure 1: Typical GBM in the right frontotemporal region. Panel A Axial contrast material-enhanced T1-weighted magnetic resonance (MR) image demonstrates a mass with irregular ring enhancement, a large area of central necrosis, perilesional edema, and early subfalcine herniation. Panel B Photograph shows a gross pathologic specimen of a frontotemporal GBM. Panel C Photomicrograph (original magnification, X40; hematoxylin-eosin stain) of a typical GBM shows a ring of viable tumor cells (straight arrows) bordering on areas of necrosis (arrowheads), referred to as pseudopalisading. Note the extensive neovascularity (curved arrows).
