Radiological and histopathological features of case #8. Axial T2-weighted image showing a circumscribed hemorrhagic lesion of the right cerebellopontine angle (a), with a low signal on T1-weighted images (b), and a peripheral enhancement on T1-weighted image with gadolinium injection (c). Ependymal features with pseudorosettes (d HPS, magnification 400\(\times \)), associated with no immunoreactivity for Olig2 (e magnification 400\(\times \)). Neurofilament immunostaining confirming the solid pattern (f magnification 400\(\times \)). Immunoexpression of H3K27M in all tumor cells (g magnification 400\(\times \)). Scale bars represent 50 µm.
