title: Suprasellar arachnoid cyst presenting with bobble-head doll movements: a report of 3 cases.
abstract: We report a series of three patients with suprasellar arachnoid cysts who presented with a rare 'bobble-head doll' syndrome. The abnormal head movements improved after surgical evacuation of the cysts in all the three cases. Various pathophysiological mechanisms involved in the bobble-head doll syndrome are discussed. The literature on suprasellar arachnoid cysts is briefly reviewed.
