A rare case of fusiform basilar trunk aneurysm

Abstract

Aneurysms in the posterior circulation and distal sites are more common among the pediatric population than among adults, with a male predominance. Symptoms of an aneurysm in the posterior circulation can include a stiff neck or severe headache due to a ruptured aneurysm, whereas an unruptured aneurysm can cause mass effects or neurological deficits. However, in children, the complete occlusion of the aneurysm while preserving the flow of the main artery can be difficult to achieve when attempting a stent-assisted coil embolization technique. A 25-month-old girl presented with left hemiparesis and was diagnosed with a basilar artery aneurysm 10 months prior, but she did not receive any specific treatment. No history of trauma and no significant familial history were recorded. Angiography showed a fusiform aneurysm on the basilar artery trunk, which was successfully occluded using stent-assisted coiling following dual antiplatelet therapy with clopidogrel and aspirin. She was discharged with the complete restoration of motor deficits.
