Chorea: a late complication of a subdural hematoma

Abstract

Subdural hematoma has rarely been implicated as a cause of chorea. We describe a case of chorea occurring several months after evacuation of a traumatic subdural hematoma. No other causes of chorea were found. In this case and one previously reported case, signs of tentorial herniation were present prior to surgery. Herniation may damage the basal ganglia, with resultant chorea.
