Traumatic aneurysms of the pericallosal artery in children. Case report.

Intracranial aneurysm in children is a rare pathology. Epidemiological studies have indicated that aneurysms in pediatric age are characterized by predominance in male subjects, a frequent great volume and a prevalently distal localization. It is assumed that these factors prove the traumatic origin (accident or birth) of the aneurysms. It is stressed that in juvenile subarachnoid hemorrhages the possibility of an aneurysm ought to be considered as an alternative to an arteriovenous malformation. A more extensive use of MR angiography is advocated in head injured patients, in order to diagnose an aneurysm before rupture. As a rule the outcome of surgical treatment is favorable provided the preoperative neurological status is not compromised.
