3%-14%的缺血性卒中患者发生纯运动神经功能缺损。纯运动性单轻瘫发生在2%-22%的纯运动性卒中患者中。作者报告了一例73岁女性患者，其孤立性手指无力是通过弥散加权平面回波磁共振成像在发病后4小时内诊断的小皮质-皮质下纯运动性卒中的唯一表现。据作者所知，以前没有报道过一例单纯运动性中风患者，其唯一表现为手指无力。提高对这种罕见的纯运动性卒中临床表现的认识，加上通过弥散加权MRI进行及时诊断的承诺，应导致早期卒中干预。
Pure motor neurologic deficits occur among 3%–14% of all patients with ischemic stroke. Pure motor monoparesis occurs among 2%–22% of patients with pure motor stroke. The authors report the case of a 73‐year‐old woman with isolated finger weakness as the sole manifestation of a small cortical‐subcortical pure motor stroke diagnosed within 4 hours of onset by means of diffusion‐weighted echoplanar magnetic resonance imaging. To the authors' knowledge, the case of a patient with pure motor stroke with finger weakness as the only manifestation has not been previously reported. Increased awareness of this rare clinical presentation of pure motor stroke coupled with the promise of prompt diagnosis by means of diffusion‐weighted MRI should lead to earlier stroke intervention.
