A germinoma in the basal ganglia developed in a 9-year-old boy with Down''s syndrome, presenting as left hemiparesis. An initial computed tomographic (CT) scan demonstrated no notable abnormalities, but serial CT scans followed the entire course of tumor growth. Subtotal removal and irradiation achieved tumor remission. This is the first case reported of intracranial germinoma associated with Down''s syndrome.
