Foster Kennedy Syndrome With Fusiform Aneurysm of Internal Carotid Arteries

The location of an aneurysm is the important factor in determining the focal signs. Garvey,1in a review of the subject of "Aneurysms of the Circle of Willis," described those aneurysms which arise from the intracranial portion of the carotid artery, from the proximal portions of the middle cerebral artery and from the circle of Willis at the point of bifurcation of these vessels as the anterior group, which presents a remarkably constant clinical picture. Also, because of the higher incidence of aneurysms of the carotid portion of the circle of Willis and the constancy of the clinical picture, the aneurysms in this location are diagnosed more frequently than those elsewhere. Localized pain in the supraorbital region on the side of the aneurysm may be present for a long time before focal signs appear. Other symptoms resulting from direct pressure on adjacent structures develop, with increase in size of
