Abstract

Traumatic intracranial aneurysms are rare, compromising less than 1% of intracranial aneurysms. The case of 20-year-old man suffered from delayed frontal intracerebral hematoma, subarachnoid hemorrhage and intraventricular hemorrhage from traumatic pericallosal aneurysm 12 days after head injury is presented. Traumatic pericallosal artery aneurysm is always near the falcine edge, is unrelated to arterial branching point. Sudden movement of brain and artery causes vessel wall injury against the stationary edge of the falx. Because of high mortality rate of ruptured traumatic aneurysm, clinical suspicion must be focused on the prompt diagnostic work-up and early treatment.
