Subarachnoid hemorrhage (SAH) due to a ruptured saccular aneurysm is uncommon in children. Pediatric traumatic aneurysms have been reported relatively frequently, tending to bleed after an interval of weeks after head injury. The authors describe three children with acute SAH after head injury caused by intracranial dissecting aneurysms. When head trauma in children is complicated by SAH in basal cisterns, dissecting aneurysms should be considered and treated, because rebleeding may occur.
