title: Development of cerebellar malignant astrocytoma at site of a medulloblastoma treated 11 years earlier. Case report.
abstract: A child treated for a desmoplastic medulloblastoma of the left cerebellar hemisphere at the age of 10 months developed a malignant astrocytoma in the same site 11 years later. Theories of origin of the second tumor, particularly in relation to concepts of the genesis of medulloblastoma in general, are discussed.
