Traumatic intracranial aneurysm: a brief review.

Traumatic intracranial aneurysms are uncommon and represent fewer than 1% of all cerebral aneurysms. They may develop after blunt or penetrating head injuries and can present both diagnostic challenges and surgical difficulties. Because traumatic aneurysms are fragile and prone to rupture, early diagnosis with cerebral angiography and prompt treatment are essential. We present two patients with traumatic aneurysms and discuss their aetiology, classification, clinical presentations, diagnosis, and treatment options.
