Pilomyxoid astrocytomas have been identified as a variant of pilocytic astrocytoma. They are listed as a novel clinico-pathological entity in the 2007 World Health Organisation (WHO) classification of tumours of the central nervous system. This tumour corresponds to a WHO grade II neoplasm whereas pilocytic astrocytoma corresponds to WHO grade I. We have encountered an infratentorial tumour with pilomyxoid features in an adult. A 25 year old man presented with tinnitus and hyperacusis. Brain MRI revealed a mass occupying the fourth ventricle. We performed partial resection, but no adjuvant therapy was given. The staining index for the anti-Ki-67 monoclonal antibody MIB-1 was less than 1% in this patient. Pilomyxoid astrocytomas are not limited to the hypothalamic/chiasmatic region in children. Additional knowledge and recognition of this entity is necessary to improve treatment of pilomyxoid astrocytoma.
