[Cerebellar medulloblastoma in a 65-year old patient]

A case of medulloblastoma arising in advanced age is presented. Histologically it has anaplastic features despite desmoplastic character and astrocytic differentiation evidenced by glial fibrillary acidic protein immunoreactivity of some neoplastic cells. Neuroblastic differentiation could not be demonstrated by the neurofilament immunoreaction. A clear correlation between advanced age of the patient, the histological subtype of medulloblastoma and the direction of the tumor differentiation could not be established.
