Traumatic intracranial aneurysms in childhood: two cases and a review of the literature

Neurosurgery. 1988 Feb;22(2):398-408. doi: 10.1227/00006123-198802000-00022.


Traumatic intracranial aneurysms in childhood are rare. To date, 67 well-documented cases in children have been reported. We present 2 additional cases and review the literature. Traumatic aneurysms can best be categorized based on mechanism of injury and location. Aneurysms secondary to penetrating trauma occur most commonly in teenage boys suffering gunshot wounds. Aneurysms secondary to nonpenetrating trauma occur at the skull base or in the periphery, with motor vehicle accidents and falls as the most common modes of injury. Skull base traumatic aneurysms most commonly involve the petrous, cavernous, or supraclinoid carotid artery and also show a predominance in teenage boys. Peripheral traumatic aneurysms can further be divided into distal anterior cerebral artery aneurysms secondary to trauma against the falcine edge and distal cortical artery aneurysms associated with an overlying skull fracture. Peripheral traumatic aneurysms tend to occur in younger patients with a less marked male predominance. Two-thirds of the patients suffered symptomatic aneurysmal hemorrhage, with an associated mortality rate of 31%. The clinical presentation, diagnosis, and treatment of traumatic intracranial aneurysms are discussed.
