Abstract

We report a case of calcified mitral and aortic stenosis revealed by a reversible ischemic stroke. A 59-year-old male patient, with background of hypertension, kidney failure, diabetes, and dyslipidemia, presented with neither acute onset of right-sided hemiparesis without aphasia nor any loss of consciousness. Head computed tomography (CT) revealed multiple rounded and amorph calcified high-density calcifications within the distal segments of both sylvian and posterior cerebral arteries. Angiographic CT of the carotids didn't reveal any stenosis or atherosclerotic plaques. Thoracic CT showed massive mitral and aortic valvular calcifications with a left ventricular hypertrophy.

摘要

我们报告一例由可逆性缺血性中风发现的钙化性二尖瓣和主动脉瓣狭窄病例。一名59岁男性患者，有高血压、肾衰竭、糖尿病和血脂异常病史，表现为无失语的右侧偏瘫急性发作，也无任何意识丧失。头部计算机断层扫描（CT）显示在大脑外侧裂和大脑后动脉远端节段内有多个圆形和无定形钙化高密度影。颈动脉血管造影CT未发现任何狭窄或动脉粥样硬化斑块。胸部CT显示二尖瓣和主动脉瓣大量钙化，伴有左心室肥厚。
