Spasmus nutans occurs in early childhood and consists of a triad of symptoms as follows: small-amplitude, rapid, horizontal nystagmus in one or both eyes asymmetrically; head nodding; and anomalous head position. Once thought to be a benign clinical entity, there are an increasing number of reports linking spasmus nutans to optic nerve and chiasmal gliomas. We describe 14 patients with spasmus nutans, none of whom were found to have a tumor with computed tomographic scanning. One patient, however, had an arachnoid cyst and an empty sella and another patient had a porencephalic cyst. The diagnosis of spasmus nutans, its implications, and its management are discussed.
点头痉挛发生于儿童早期，由以下三联征症状组成：单眼或双眼不对称性的小幅度、快速水平性眼球震颤；点头动作；以及异常头位。曾经被认为是一种良性临床病症，现在越来越多的报告将点头痉挛与视神经及视交叉胶质瘤联系起来。我们描述了14例点头痉挛患者，经计算机断层扫描，无一例发现患有肿瘤。然而，1例患者有蛛网膜囊肿和空蝶鞍，另1例患者有脑穿通性囊肿。本文讨论了点头痉挛的诊断、其影响及处理。
