Occlusion of middle cerebral artery (MCA) is generally associated to severe stroke and poor prognosis; however a few patients with mild to moderate presentation and long-term reversibility of neurological deficits have been reported. A 66-year-old male presented with left-side weakness and dysarthria (NIHSS score 7), which progressively resolved within a few days; ischaemic lesion of the anterior arm of the right internal capsule was found at brain CT obtained 72 h after presentation. Transcranial Colour Doppler showed absence of flow of the right MCA. Cerebral angiography showed occlusion of the right MCA that was retrogradely revascularised by leptomeningeal collaterals. Non-invasive intracranial vascular examinations could identify major intracranial artery lesions in patients who present with mild to moderate stroke symptoms. These patients could be identified and followed to clarify their best treatment and prognosis.
大脑中动脉（MCA）闭塞通常与严重中风及不良预后相关；然而，已有报道称少数患者表现为轻度至中度症状且神经功能缺损具有长期可逆性。一名66岁男性出现左侧肢体无力和构音障碍（美国国立卫生研究院卒中量表[NIHSS]评分为7分），症状在数天内逐渐缓解；就诊72小时后行脑部CT检查发现右侧内囊前肢有缺血性病变。经颅彩色多普勒显示右侧大脑中动脉无血流信号。脑血管造影显示右侧大脑中动脉闭塞，由软脑膜侧支逆行再通。非侵入性颅内血管检查可识别出现轻度至中度中风症状患者的主要颅内动脉病变。这些患者可被识别并随访，以明确最佳治疗方案和预后。
