title: Coil embolization of a traumatic intracranial aneurysm of the distal part of the azygos anterior cerebral artery followed up for 4 years.
abstract: Traumatic intracranial aneurysms are rare, usually occur as a result of traffic accidents, and are associated with high rates of morbidity and mortality. A 12-year-old boy was admitted for treatment of cerebral hemorrhage in the left frontal lobe, 3 months after a traffic accident. Angiography revealed an intracranial aneurysm of the distal part of the azygos anterior cerebral artery (ACA). The maximum size of this aneurysm was 9.5 mm. Coil embolization was successfully performed with preservation of the parent arteries. Angiography performed at the 4-year follow-up examination revealed no abnormalities. The present case showed that primary coiling may allow aneurysm occlusion along with parent vessel preservation in selected cases of traumatic intracranial aneurysm of the distal part of the azygos ACA.
