Endovascular treatment of traumatic intracranial aneurysm in an infant. A case report.

SUMMARY: Traumatic intracranial aneurysms in children are rare and mostly related to skull fracture or rapid decelerating closed head injury.We report the case of an infant who developed intracranial aneurysm after minor head trauma and managed by endovascular treatment. A seven-month-old infant presented with delayed intracranial hemorrhage following minor head trauma. Cerebral angiography disclosed a multilobulated fusiform aneurysm involving the right anterior cerebral artery (ACA) distal to the anterior communicating artery. Endovascular treatment of the aneurysm was performed and the infant made an excellent recovery during six months clinical and radiological follow-up. Delayed presentation of intracranial hemorrhage with acute deterioration in the infant after head trauma warrants angiography for proper diagnosis and management of the traumatic aneurysm, which has a high mortality rate after rupture and rebleeding. Endovascular treatment of traumatic aneurysm is feasible in infants, and occlusion of distal intracranial arterial aneurysms can be safely and precisely achieved using current coil technology.
