The incidence of intracranial aneurysms in the pediatric population is low, and surgical clipping remains a good long-term treatment option. However, posterior circulation aneurysms are even more complex to manage in children than in adults. We report a case of a giant aneurysm of the posterior cerebral artery in a 10-year-old boy presenting with subarachnoid hemorrhage. Endovascular treatment with platinum coils was performed with total occlusion of the aneurysm and the affected arterial segment without complications. The patient achieved good recovery, and a late control angiogram confirmed exclusion of the aneurysm. Occurrence of special features of cerebral aneurysm in children, in comparison to adults, is also described. Parent artery sacrifice is an effective therapeutic option, but long-term follow-up is necessary to avoid recurrence and rebleeding.
