FIGURE 4.
Low-grade astrocytoma, subtype indeterminate, with broad cytoplasmic processes and prominent nucleoli. Axial T2-weighted magnetic resonance imaging demonstrating a well-circumscribed tumor in the right insular region (A). The tumor showed uniform enhancement on postcontrast T1-weighted magnetic resonance imaging (B). Large cells with thick processes and prominent nucleoli in an intraoperative smear (phloxine-hematoxylin; 600×) (C). Another LGSI with ample eosinophilic cytoplasm and prominent nucleoli (hematoxylin and eosin; 400×) (D).
