Ventriculoperitoneal shunt related meningioma following excision and radiotherapy for glioma.

A 25-year-old man with a history of childhood cerebellar glioma treated by surgical removal, radiotherapy and a ventriculoperitoneal (VP) shunt presented with a 5 month history of frontal headaches. Imaging revealed a mass surrounding his shunt, which was surgically removed, with the shunt left in situ. Histopathological examination revealed an atypical and invasive meningioma. A similar case of a meningioma related to a shunt appears in the literature, again in the context of radiotherapy following removal of a previous neoplasm. Copyright 1999 Harcourt Publishers Ltd.
