A 19-year-old woman reported progressively worsening involuntary head movements since the age of 7. She had visited multiple hospitals and been labelled as having a functional disorder. Detailed evaluation identified a large supra-sellar arachnoid cyst with hydrocephalus. We made a diagnosis of bobble-head doll syndrome, which is only very rarely associated with suprasellar arachnoid cyst. Her symptoms improved rapidly following endoscopic third ventriculostomy with cyst fenestration and gradual decompression of the ventricles. Clearly, not all suppressible movements should be labelled as psychogenic.

摇头娃娃综合征伴鞍上蛛网膜囊肿

一名 19 岁女性报告说，自 7 岁起，不自主的头部运动逐渐恶化。她曾去过多家医院，并被贴上功能障碍的标签。详细评估确定了一个大的鞍上蛛网膜囊肿伴脑积水。我们做出了摇头娃娃综合征的诊断，这种综合征很少与鞍上蛛网膜囊肿相关。在内窥镜下第三脑室造瘘术、囊肿开窗术和心室逐渐减压后，她的症状迅速改善。显然，并非所有可抑制的运动都应标记为心因性的。
