Traumatic intracranial aneurysm after blunt trauma.

Traumatic intracranial aneurysms are rare and represent less than 1% of all cerebral aneurysms. This type of aneurysm develops after blunt or penetrating head trauma. Surgical clipping and/or endovascular occlusion are the definitive treatments. This report describes the very unusual case of a patient who has survived for 2 years with conservative management alone.
