Intracranial Aneurysm Epidemiology

Intracranial aneurysms are acquired lesions (5-10% of the population), a fraction of which rupture leading to subarachnoid hemorrhage with devastating consequences.

In a Korean population study, the standardized incidence of intracranial aneurysm was 52.2/100,000 person-years. Older age, female sex, hypertension, history of heart disease, and family history of stroke were independent risk factors for intracranial aneurysm ¹⁾.

Intracranial aneurysms (IAs) are rare in the general pediatric population and account for <2% of all cerebral aneurysms. Only 7 children with sickle hemoglobinopathy and IAs have been reported, the majority of which were discovered after rupture.
