Ependymoma - Pathology
•
Gd I – subependymoma and myxopapillary
ependymoma
•
Gd II – Ependymoma
•
Gd III – Anaplastic ependymoma. Presence of
hypercellular areas, necrosis, microvascular
proliferation, high mitotic indices confer worse PFS
Anaplastic histology + infratentorial location carries
increased mortality risk in younger children
Supratentorial location associated with higher mortality
in older patients
