title: December 1996--cervicomedullary tumor.
abstract: A cervicomedullary tumor in a 22-month-old female with an eight-month history of symptoms showed the histological features of a pilocytic astrocytoma but had many areas of palisading cells identical to those described in polar spongioblastomas. The tumor recurred 18 months later and showed predominately pilocytic features. The case is used to discuss polar spongioblastomas and tumors which can histologically simulate them.
