Systemic sclerosis is a multisystem autoimmune collagen disease where structural and functional abnormalities of small blood vessels prevail. Transient ischemic attacks, ischemic stroke, and hemorrhage have been reported as primary consequence of vascular central nervous system affection in systemic sclerosis. Magnetic resonance imaging is considered to be the most sensitive diagnostic technique for detecting symptomatic and asymptomatic lesions in the brain in cases of multifocal diseases. The objective of this study is to detect subclinical as well as clinically manifest cerebral vasculopathy in patients with systemic sclerosis using magnetic resonance imaging. As much as 30 female patients with systemic sclerosis aged 27-61 years old, with disease duration of 1-9 years and with no history of other systemic disease or cerebrovascular accidents, were enrolled. Age-matched female control group of 30 clinically normal subjects, underwent brain magnetic resonance examination. Central nervous system (CNS) involvement in the form of white matter hyperintense foci of variable sizes were found in significantly abundant forms in systemic sclerosis patients on magnetic resonance evaluation than in age-related control group, signifying a form of CNS vasculopathy. Such foci showed significant correlation to clinical features of organic CNS lesion including headaches, fainting attacks and organic depression as well as to the severity of peripheral vascular disease with insignificant correlation with disease duration. In conclusion, subclinical as well as clinically manifest CNS ischemic vasculopathy is not uncommon in systemic sclerosis patients and magnetic resonance imaging is considered a sensitive noninvasive screening tool for early detection of CNS involvement in patients with systemic sclerosis.
系统性硬化症是一种多系统自身免疫性胶原病,小血管的结构和功能异常占主导地位。在系统性硬化症中,血管中枢神经系统受累可导致短暂性脑缺血发作、缺血性卒中和出血等原发性后果。磁共振成像被认为是检测多灶性疾病中脑内症状性和无症状性病变的最敏感诊断技术。本研究旨在使用磁共振成像检测系统性硬化症患者的亚临床和临床显性脑血管病。共纳入 30 名年龄在 27-61 岁之间、病程 1-9 年、无其他系统性疾病或脑血管意外史的女性系统性硬化症患者。年龄匹配的 30 名临床正常女性对照者接受了脑部磁共振检查。与年龄相关的对照组相比,磁共振评估显示系统性硬化症患者中存在大量的中枢神经系统(CNS)白质高信号灶,这些病灶大小不一,提示存在 CNS 血管病。这些病灶与有机 CNS 病变的临床特征(包括头痛、晕厥发作和器质性抑郁)以及外周血管疾病的严重程度显著相关,与病程无显著相关性。总之,亚临床和临床显性 CNS 缺血性血管病在系统性硬化症患者中并不罕见,磁共振成像被认为是一种敏感的非侵入性筛查工具,可用于早期发现系统性硬化症患者的 CNS 受累。
