Fibromuscular dysplasia (FMD) is a non-inflammatory, non-atherosclerotic disease resulting in stenosis and arterial wall weakening of typically medium-sized arteries. Intracranial aneurysm is an uncommon presentation of FMD, with a significant proportion presenting in the posterior circulation. Presented is the rare case of an adult female with left-sided stroke with angiographically-confirmed left middle cerebral artery FMD, with pan-scanning unremarkable for other demonstrable evidence of FMD. The patient's neurological deficits completely resolved. The patient was stable for discharge home on antiplatelet therapy. Appropriate imaging and screening should be performed to ensure FMD is localized versus systemic. Patients with intracranial FMD should be protected from cerebrovascular events with antiplatelet therapy.
纤维肌发育不良（FMD）是一种非炎症性、非动脉粥样硬化性疾病，可导致典型的中等大小动脉狭窄和动脉壁变薄。颅内动脉瘤是FMD的一种罕见表现，其中很大一部分出现在后循环。本文介绍了一例罕见病例，一名成年女性因左侧中风就诊，血管造影证实为左侧大脑中动脉FMD，全身扫描未发现其他可证实的FMD证据。患者的神经功能缺损完全恢复。患者在接受抗血小板治疗后病情稳定，可以出院回家。应进行适当的影像学检查和筛查，以确保FMD是局限性的而非全身性的。颅内FMD患者应接受抗血小板治疗，以预防脑血管事件。
