Intracranial aneurysms in children are unusual. Less than 1% incidence in unselected series has been found, and vertebrobasilar aneurysms in children (7%) are as rare as in adults. In this series, 49 patients were less than 18 years old, and in this group males dominated (27), as is the case also in pediatric anterior circulation aneurysms. Half of the cases presented with bleeding. Most, even those with ruptured aneurysms, had mass effect as three-fourths of the aneurysms were of giant size; only five aneurysms were small. More than half of the aneurysms were fusiform. This unknown arteriopathy was local on that intracranial arterial segment, usually on basilar or posterior cerebral arteries (PCAs), and no special general vasculopathies or system diseases were observed. (Mid)basilar trunk and PCA aneurysms were most common and in giant form in most cases. Multiple aneurysms were seldom found (5); interestingly three of them were giant extradural internal carotid aneurysms associated with one large and two giant (mid)basilar trunk aneurysms. Three patients had arteriovenous malformations (AVMs).
