Contrast-enhanced MRI shows recurrence of a large heterogeneous and hemorrhagic mass with intense enhancement at right cerebellar hemisphere with adjacent tentorial enhancement and intraventricular extension. There is evidence of extension to suprasellar and pineal region. In addition, a diffuse and relatively thick mass forming ependymal enhancement of lateral and third ventricles with thick and nodular enhancement of fourth ventricle and foramen of Monro is observed. Ill-defined margin and parenchymal enhancement at right frontal lobe is noted too,
Histopathologic findings of the tumor that was operated 9 months ago confirmed Desmoplastic nodular type of medlloblastoma.
