In this report, the authors analyzed retrospectively 20 cases of pure traumatic basal ganglia hemorrhage(TBGH), which were diagnosed and treated in our hospital between January 1990 and June 1995. The TBGH incidence constitutes 1.4% of all head trauma. It occures were commonly among the younger male patient groups. The main causes of trauma was motor vehicle accidents. The overall mortality rate was 15%. Low initial GCS score, fixed pupillary reflex, pathologic reflex, poor motor response and large hematoma size were all poor prognostic factors, resulting a high mortality or passimistic outcome.
