A rare central nervous system embryonal tumour characterised by embryonal cells arranged in multilayered rosettes and displaying one of three morphological patterns: embryonal tumour with abundant neuropil and true rosettes, ependymoblastoma, or medulloepithelioma. The tumours typically have a C19MC alteration or (rarely) a DICER1 mutation and correspond to WHO grade IV. They are mostly localised intracranially, rarely in the spinal cord, and commonly cause signs and symptoms of elevated intracranial pressure, sometimes seizures and focal neurological signs.
