title: Subependymoma: a case report with ultrastructural study.
abstract: A case history illustrating the potential clinical significance of subependymoma is presented. Fine structural studies indicate that the tumor is composed of cells having the cytoplasmic features of ependyma, astrocytes, and transitional cells. Its composition and structure are alike those in the adult mammalian subependymal layer.
