Ependymoblastoma

Ependymoblastoma is a rare type of primitive neuroectodermal tumor (PNET) that usually occurs in young children under the age of 2 and is histologically distinguished by the production of ependymoblastic rosettes. It is associated with an aggressive course and a poor prognosis.

Supratentorial ependymomas and ependymoblastomas show the following characteristic features of CT scans: Calcification: The incidence of calcification was 50% in ependymoma-group, and 100% in ependymoblastoma-group.

In ependymoma-group a smooth ring-enhancement pattern and the strongly enhanced mural nodule-like contour were found, but in ependymoblastoma-group, the cyst wall was enhanced in irregular shape.
