Pontine ischemia usually results in focal deficits such as hemiparesis, facial palsy, dysarthria, disorders of eye movements or vertigo. Although rarely described, involuntary abnormal movements and "convulsions" due to pontine lesions can also occur. Here we describe a 67-year-old woman with hypertension who presented with a tonic movement mimicking a versive seizure in the acute phase of bilateral pontine ischemia. Post-stroke movement disorders are well known. They are usually associated with supratentorial lesions and rarely occur in the acute phase, but "seizure-like" episodes can be seen in pontine ischemia. Awareness of this rare phenomenon is useful for the management of acute stroke patients.
桥脑缺血通常导致局灶性缺陷，如偏瘫、面瘫、构音障碍、眼球运动障碍或眩晕。尽管很少描述，但由于桥脑病变也可能发生不自主的异常运动和“抽搐”。在这里，我们描述了一位 67 岁的女性高血压患者，她在双侧桥脑缺血的急性期出现了一种模仿扭转性发作的强直运动。中风后运动障碍是众所周知的。它们通常与幕上病变有关，很少在急性期发生，但在桥脑缺血中可以看到“类似癫痫发作”的发作。了解这种罕见现象对急性中风患者的治疗很有用。
