Ependymoblastoma: CT and MRI demonstration

Ependymoblastoma is a rare and highly malignant brain tumor considered to be a subtype of primitive neuroectodermal tumors. We presented a case of ependymoblastoma in a 14-year-old girl. CT and MRI showed a large, supratentorial, paraventricular tumor with cystic and irregularly enhancing solid components. Foci of intratumoral hemorrhage and absence of peritumoral edema were also demonstrated. We claimed that ependymoblastoma should be included in the differential diagnosis of a well-circumscribed, large, supratentorial tumor without perifocal edema in a child or young adult similar to this case.
