Spasmodic torticollis, once thought to be psychogenic, is now recognized as an extrapyramidal movement disorder. A patient with onset of classical torticollis after closed head injury and intracranial hypertension is described. The patient had no clinical or radiologic evidence of brain stem dysfunction, but brain stem auditory evoked potentials suggested pontomesencephalic conduction disturbance ipsilateral to head and neck movements. This finding accords with some previous clinical and experimental evidence that pontomesencephalic structures ipsilateral to the movements may be involved in torticollis. The observation suggests that spasmodic torticollis may develop as a sequel to trauma in head-injured patients and should be differentiated from posttraumatic seizures.
痉挛性斜颈曾被认为是心因性的，现在被公认为是一种锥体外系运动障碍。本文描述了一名在闭合性颅脑损伤和颅内高压后出现典型斜颈的患者。该患者没有脑干功能障碍的临床或影像学证据，但脑干听觉诱发电位提示与头部和颈部运动同侧的脑桥中脑传导障碍。这一发现与之前一些临床和实验证据相符，即与运动同侧的脑桥中脑结构可能参与了斜颈的发病。该观察结果表明，痉挛性斜颈可能作为头部受伤患者创伤后的后遗症出现，应与创伤后癫痫相鉴别。
