MATERIALS AND METHODS
A-28-year-old man with traffic accident was examined with brain CT & cerebral angiography.
RESULTS
l) Brain CT:lnitial scan shows multiple skull fractures involving right frontal bones with subarachnoid hemorrhage and pneumocephalus. Follow-up scan shows intracerebral hemorrhage at bilateral frontal lobes. 2) Cerebral angiography:A traumatic aneurysm which is slowly filling and delayed emptying is noted at the junctional portion of A1 and A2 segment of the anterior cerebral artery.
