Functional neurological disorder is a condition in which a patient has physical findings that are not compatible with anatomical boundaries, have no structural substrate and are not representable of an established disease. General anaesthesia and surgery have been previously reported as precipitating factors for functional disorders and mostly involve dissociative (non-epileptic) seizures. We report a patient with no psychiatric history or prior abnormal examination who developed sudden onset functional tetraplegia and sensory disturbances immediately after elective surgery, and who was subsequently discharged home several days later after nearly complete resolution of neurologic deficits. We highlight the features of this syndrome, including its unique postoperative presentation, unusual resolution and absence of any identifiable psycho-dynamic mechanism. We also introduce the tripod sign as a useful clinical tool in identifying functional tetraplegia.

ICU 中的 Charcot：术后功能性四肢瘫痪

功能性神经障碍是指患者的身体检查结果与解剖边界不符、没有结构性基础并且不能代表已确定的疾病的病症。之前曾报道全身麻醉和手术是功能障碍的诱发因素，主要涉及分离性（非癫痫）癫痫发作。我们报告了一名没有精神病史或既往检查异常的患者，他在择期手术后立即出现突然发作的功能性四肢瘫痪和感觉障碍，几天后在神经功能缺损几乎完全解决后出院回家。我们强调了这种综合征的特征，包括其独特的术后表现，异常的解决和缺乏任何可识别的心理动力机制。我们还介绍了三脚架标志作为识别功能性四肢瘫痪的有用临床工具。
