Ischemic stroke is a rare complication of Churg-Strauss syndrome (CSS) and its pathogenesis has not been well clarified yet. We report a case of cerebral infarction in a patient with CSS due to embolism from a thrombus on the wall of the aorta.
A 39-year-old man had multiple cerebral infarctions with symptoms of mild left hemiparesis and reduced vision. He was clinically diagnosed to have CSS based on remarkable eosinophilia, history of asthma, sinusitis, pulmonary infiltrates, and histologically proven extravascular eosinophilic infiltrates in the specimen of gastric mucosa. Cerebral angiography did not show any stenotic lesions in cerebral arteries. A thrombus was detected on the wall of the aorta by transesophageal echocardiography, which was considered as the source of embolism. The thrombus resolved on follow-up examination 3 months after the onset of the stroke.
This is the first case report on cerebral infarction caused by aortogenic thromboembolism in a CSS patient. Other than cerebral vasculitis, embolism from cardiovascular system, including the wall of the aorta, is a possible cause of cerebral infarctions in a CSS patient.
缺血性中风是变应性肉芽肿性血管炎(CSS)的一种罕见并发症,其发病机制尚未完全阐明。我们报告1例CSS患者因主动脉壁血栓形成导致栓塞而发生脑梗死的病例。
一名39岁男性出现多发性脑梗死,伴有轻度左侧偏瘫和视力下降症状。根据显著的嗜酸性粒细胞增多、哮喘病史、鼻窦炎、肺部浸润以及胃黏膜标本组织学证实的血管外嗜酸性粒细胞浸润,临床诊断为CSS。脑血管造影未显示脑动脉有任何狭窄病变。经食管超声心动图在主动脉壁上检测到血栓,该血栓被认为是栓塞的来源。血栓在中风发作3个月后的随访检查中消失。
这是首例关于CSS患者因主动脉源性血栓栓塞导致脑梗死的病例报告。除了脑血管炎外,包括主动脉壁在内的心血管系统栓塞是CSS患者脑梗死的一个可能原因。
