We report here a 70 year-old male on maintenance hemodialysis who presented non-paralytic pontine exotropia. Brain MRI showed new right pons infarct. Transthoracic and transesophageal echocardiography revealed a mobile calcification at posterior mitral leaflet with rapid growing compared to 14 days ago. Neurological symptoms disappeared at least 10 days by a treatment with aspirin. Calcification reduced by a follow-up transthoracic echocardiography after 90 days from the beginning of neurological symptoms. We diagonosed him with cerebral infarction during the course of mobile mitral annular calcification-related calcified amorphous tumor. Mobile mitral annular calcification-related calcified amorphous tumor would be a cause of cerebral infarction, we need to be careful to check a transthoracic echocardiography regularly because of necessity.
我们在此报告一名70岁维持性血液透析男性患者，其出现非麻痹性脑桥外斜视。脑部MRI显示右侧脑桥有新发梗死灶。经胸和经食管超声心动图显示二尖瓣后叶有一活动钙化灶，与14天前相比生长迅速。经阿司匹林治疗至少10天后神经症状消失。自神经症状出现90天后，经胸超声心动图随访显示钙化灶缩小。我们诊断其为移动性二尖瓣环钙化相关钙化性无定形肿瘤病程中的脑梗死。移动性二尖瓣环钙化相关钙化性无定形肿瘤可能是脑梗死的一个病因，因此有必要定期仔细检查经胸超声心动图。
