Ependymal astrocytoma: subependyoma or subependymal glomerate astrocytoma [PDF]
Arquivos de Neuro-Psiquiatria, 1982 The histological study of four cases and one by electron microscopy of subependyomomas allowed us to obtain morphostructural characteristics of ependymocytes and astrocytes. Comparing these findings to those of the present day literature, we propose to name these tumours ependymal astrocytomas.

PSEN1 Expression Identifies a Developmentally Distinct Favourable-Prognosis State in SHH α Medulloblastoma. [PDF]
Int J Dev NeurosciHigh PSEN1 expression identifies a favourable‐prognosis state in SHH α medulloblastoma and is associated with a reproducible transcriptional programme related to cellular homeostasis and development. Its broad expression during cerebellar development and across paediatric brain tumours suggests that its prognostic significance reflects the specific ...

, 2016 Pilocytic astrocytoma (PA) is the most common pediatric brain tumor in children. PAs are a distinct histologic and biologic subset of glioma that have a slow growth rate and may even spontaneously regress. These tumors tend to arise in the cerebellum and chiasmatic/hypothalamic region, but can also occur in other regions of the central nervous system ...
