Traumatic distal anterior cerebral artery aneurysm in a 3-year-old child: An uncommon but notable case

Aneurysm in paediatric population is a relatively less reported vascular pathology. In contrary to degenerative and dysplastic causes as in their adult counterpart, the mechanism lies either in a congenital defect in vessel wall or following some traumatic event. Traumatic intracranial aneurysms (TICA) are again not a common occurrence. TICAs constitute <1% of all intracranial aneurysms. They can occur following blunt or penetrating head trauma and are more common in the paediatric population. Traumatic aneurysms are typically associated with an acute episode of delayed intracranial haemorrhage with an average time from initial trauma to aneurysm haemorrhage of approximately 21 days. The youngest case reported for a traumatic distal anterior cerebral artery (ACA) aneurysm is of a 6-week old child due to shaken baby syndrome. We report an interesting and rare case of a traumatic distal ACA aneurysm in a 3-year-old child.
