肿瘤性坏死和血管增生都比较明显，尤其是血管周的细胞呈上皮样，GFAP（+），所以我们最后诊断胶质母细胞瘤（WHOⅣ级）。

 从上述图片来看，星形细胞瘤（WHO 3级）是没问题，但少枝胶质细胞瘤成分似乎不明显。

The MRI image is very helpful. The photomicrographs are somewhat blue in background, but I could see focal tumor necrosis and vascularp proliferation. There are elongated neoplastic astrocytes, but the overall cellularity is not very high in the photos. Could you tell whether mitotic figures are found easily? And whether there are hypercellular areas not shown in the photos? More importantly, are there dysplastic neurons in the neoplasm? My suspicion is that this is WHO grade IV glioblastoma, but I would like to rule out a ganglioglioma because of low cellularity.
