Cerebellar mutism after surgery for posterior fossa tumours in childre n is a well-described, though rare, entity. Most of these rumours are located in the region of the cerebellar vermis extending to the hemisp heres. The authors report a case of cerebellar mutism in an 8-year-old boy who underwent surgical evacuation of a spontaneous vermian haemat oma. We feel that his mutism was an extreme form of cerebellar dysarth ria.
