title: The A1 syndrome: a clinical entity?
abstract: We report two patients in whom suprasellar extension of pituitary tumours resulted in a motor deficit, in one case as the clinical presentation and in the other one as a consequence of trans-sphenoidal surgery. We emphasize the importance of the involvement of the initial segment of the anterior cerebral artery in pituitary tumours.
