[Traumatic false aneurysms of intracranial artery]

The authors report a case of intracranial traumatic aneurysm at young a 21 years old patient. He presented with recurrent epistaxis 3 months after craniofacial trauma. An aneurysm of the left carotid artery was diagnosed at cerebral angiography. Endovascular treatment was performed with favorable outcome. In spite of their rarity, posttraumatic intracranial aneurysms should be suspected in patients with recent or remote history of trauma, even minor, presenting with secondary clinical deterioration, in order to carry out emergent angiographic exploration, before contemplating definitive surgical or endovascular treatment.
