title: Traumatic basal subarachnoid hemorrhage due to rupture of the posterior inferior cerebellar artery--case report.
abstract: A 20-year-old male presented with traumatic basal subarachnoid hemorrhage after being involved in a fight. Antemortem clinical examinations could not exclude the possibility of rupture of abnormal blood vessels because of the absence of external injuries. Careful postmortem examination of the head and neck regions and histological examination of the intracranial arteries demonstrated traumatic rupture of the left posterior inferior cerebellar artery due to a fist blow to the jaw. This case indicates the need for careful autopsy examination for the differentiation of traumatic and non-traumatic basal subarachnoid hemorrhages.
