Aneurysm of a superior cerebral vein.
Among 880 specimens of cerebral dura mater with enclosed sinuses, one had a sharply delineated bulbous conformation of the distal segment of a superior cerebral vein. There was no evidence of an arteriovenous malformation. Early plaque formation was present in the inner aspect of the thick wall of the dilated segment of vein.
