Traumatic intracranial aneurysm is rare and mostly due to blunt head injury. High mortality rate up to 50% is reported in the literature. Early diagnosis and appropriate management is essential for this fatal disease. We present a rare case of pseudoaneurysm over left-side posterior communicating artery after traumatic head injury. Avulsion of the posterior communicating artery was noted intra-operatively and then clipping of the proximal stump was arranged. There was no delayed hemorrhage after the operation. After review of the literature, there is no definite management for this kind of traumatic intracranial pseudoaneurysm. Here, we present the fourth case of posterior communicating artery traumatic pseudoaneurysm, which presents appropriate outcome after surgical intervention of clipping proximal stump of the avulsed artery.
