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.
