Gliomas ependymomas

Most grade II to IV gliomas infiltrate CNS tissue, which makes total resection difficult to impossible. Exceptions include certain ependymomas and xanthoastrocytomas. [Pg.833]

Astrocytomas are among the most fibrillar of CNS neoplasms, more fibrillar than other gliomas except tany-cytic ependymomas and subependymomas (see Table... [Pg.833]

The cellular conformations of ependymomas vary between fibrillar and epithelial, posing special problems of differentiation not only from other gliomas but also from carcinomas and meningiomas (see Tables 20.5 and... [Pg.842]

The oligoastrocytoma is a mixed glioma composed of both astrocytoma and oligodendroglioma, as described in the respective sections on these tumors (see Fig. 20.10A). Much less common than oligoastrocytoma, mixed gliomas may have a component of ependymoma. ... [Pg.846]

Glioneuronal tumors are a heterogeneous group of tumors in need of further dehnition. When their definition is complete, the glioneuronal tumors may encompass other focally synaptophysin-positive tumors also interpreted as odd variants of gliomas, such as oligodendrogliomas and ependymomas with neuronal differentiation. [Pg.855]
