In this paper we report a child who had extensive neoplastic infiltration of the meninges which defied clinical detection. We believe that any patient with a past or present history of tumor who presents with increased intracranial pressure should be presumed to have intracranial neoplastic involvement, even in the face of negative diagnostic studies. As in this case, other causes of increased pressure should be systematically intracranial excluded.
