Giant supratentorial meningeal haemangiopericytoma in a newborn.

A brain tumour in a newborn is rare. The incidence of congenital tumours is 0.34 per one million births. We report a case of a huge right hemispheric tumour operated upon successfully in a child 5 days old, who had a total tumoural excision and an uneventful outcome with 5 months follow up. This tumour appears to be the first meningeal haemangiopericytoma described in a newborn. Adequate treatment and histological findings are discussed. meningeal haemangiopericytomas are now considered as originating in pericytes, in the light of recent immunopathological results, and are to be separated from true meningiomas.
