Strokes are a major cause of disability in systemic lupus erythematosus (SLE). Classical neurological manifestations are rare at onset. The use of thrombolytic therapy improves clinical outcome in eligible stroke patients who present early. Modern imaging modalities augment decision making. This 37-year-old woman presented with an acute stroke with National Institute of Health stroke scale 10. The CT showed a hyperdense middle cerebral artery (MCA) dot sign. The magnetic resonance angiography revealed focal thromboembolic occlusion at the insular MCA segment (M2). Intravenous recombinant tissue plasminogen activator (rtPA) was administered with successful recanalization. The present case was a rare event for rtPA use in acute MCA occlusion with underlying latent lupus. Acute vascular event thrombolysis as the presenting manifestation of autoimmune disease has not previously been encountered on literature review. Stroke pathophysiology in conditions of hypercoagulability is a significant clinical entity where the implication for thrombolytic use requires further studies. An ischemic stroke with underlying connective tissue disease benefits from timely multimodal brain imaging and should be considered for reperfusion.
中风是系统性红斑狼疮(SLE)导致残疾的主要原因。典型的神经学表现发病时罕见。对于早期就诊的符合条件的中风患者,使用溶栓治疗可改善临床结局。现代影像学检查手段有助于决策制定。这位37岁女性因急性中风就诊,美国国立卫生研究院卒中量表评分为10分。CT显示大脑中动脉(MCA)有高密度点状征。磁共振血管造影显示岛叶MCA段(M2)有局灶性血栓栓塞性闭塞。给予静脉注射重组组织型纤溶酶原激活剂(rtPA)后成功再通。本病例是rtPA用于潜在狼疮基础上的急性MCA闭塞的罕见情况。急性血管事件溶栓作为自身免疫性疾病的首发表现,在文献回顾中此前未曾遇到过。高凝状态下的中风病理生理学是一个重要的临床实体,其中溶栓应用的意义需要进一步研究。伴有潜在结缔组织病的缺血性中风受益于及时的多模态脑成像,应考虑进行再灌注治疗。
