case_images: MRI of the head showed a 9 x 8 x 8 cm supratentorial tumour on the left side (Figure 1(a)). INI1 was negative in the tumour cells but positive in endothelial and inflammatory cells (Figure 1(b)). Most cells were negative for S-100 and PGR, CD34, Desmin, IDH1, and NeuN. IHC for p21 and p53 showed similar number of stained nuclei, indicating no probable p53 mutation.
