There is focal pseudopalisaded tumor necrosis in this infiltrative malignancy, which makes me believe it is probably WHO grade IV glioblastoma. These photos suggest that the cryosections prepared were air-sried and not immediately fixed in formalin before being stained. H&E staining was also inadequate in that eosin is barely detectable.

I think this is WHO grade IV glioblastoma with focal tumor necrosis and vascular/endothelial proliferation. Neoplastic cells infiltrate the surrounding brain parenchyma with focal collection of hyalinized blood vessels. I do not see a definite component of sarcoma or oligodendroglioma.
