Cerebral Aneurysm

Intracranial aneurysms in children are rarely encountered in the scope of neurosurgical practice. Although clearly rare, the exact incidence of cerebral aneurysms in children is difficult to ascertain. Unlike their adult counterparts, childhood aneurysms are typically symptomatic at the time of their diagnosis. Childhood aneurysms most often become symptomatic from birth to age 6 and then from 8 years to adolescence. Posterior circulation aneurysms are more prevalent in children than in adults by nearly threefold. Traumatic aneurysms typically develop from direct penetrating injury or in association with a closed-head injury.
