Traumatic aneurysms of the internal and external carotid arteries. One case and a review of the literature.

The case of a female patient with two traumatic aneurysms diagnosed by serial angiography is reported. The first aneurysms, located on the orbito-frontal branch of the left anterior cerebral artery, was removed. The second aneurysm involving the right middle meningeal artery was treated by endovascular embolization. The causes and physiopathology of such lesions are reviewed. The frequency of traumatic cerebral aneurysms has been reduced by the routine use of computed tomography. Aggressive treatment of these aneurysms is advocated because of their natural history.
