[Cerebellar medulloblastoma in childhood: supratentorial metastasis].
Reports on supratentorial metastases of medulloblastoma are infrequent. Computed tomography has increased the possibilities of detecting then in a silent clinical phase. Five children with supratentorial metastasis of medulloblastoma were retrospectively reviewed. Diagnosis was established by cranial CT between three and sixty months following treatment of the tumor. Dissemination through the ventricular system was found in all the cases. Other lesions were found in the transition zone between the white and grey matter (2/5) and the left frontal lobe (1/5). The routes of dissemination are discussed. Early diagnosis of supratentorial metastasis of medulloblastoma require periodic cranial CT or magnetic resonance imaging (MRI), at least during the first years after diagnosis and treatment of the primary tumor.
