横纹肌样脑膜瘤WHO3级

 考虑巨细胞胶质母细胞瘤。

 胶质肉瘤。

The photos are probably best characterized as from a WHO grade IV glioblastoma. My only concern is that figures 2 and 3 have small cell areas, which if are parts of the neoplasm tend to make me wonder about a PNET with glial/astrocytic differentiation. I would do GFAP, synaptophysin and NSE immunostains for confirmation. I do not believe this is a rhabdoid meningioma or a gliosarcoma.

 Are there any differences between glioblastoma and gliosarcoma?I want to ask mjma

In most textbooks and research artiels, glioblastoma and gliosarcoma have the same grave prognosis. Therefore, the main difference between the two is in histopathology. One has areas of sarcoma (usually fibrosarcoma) in addition to classic glioblastoma.

I have understood.Thank you so much for your help

首先考虑多形性胶质母细胞瘤，形态不太象横纹肌样脑膜瘤，就形态而言比横纹肌样脑膜瘤恶性程度要高。
