Abstract
Normal anatomy of the anterior cerebral vein is briefly described. In angiography the anterior cerebral vein indicates the position of the lamina terminalis just above the optic chiasm. In cases of intrasellar masses with suprasellar extension the anterior cerebral vein is elevated and indicates the superior margin of the tumor. In highly vascular frontal tumor the anterior cerebral vein is hypertrophic and serves as a drainer of the tumor. In choroid plexus papilloma of the third ventricle the anterior cerebral vein is depressed and anteriorly displaced. This indicates dilatation of the third ventricle. Usefulness of the anterior cerebral vein in diagnosing suprasellar extension of intrasellar masses is stressed.
