We report the case of a 62-year-old male on long-term hemodialysis who was admitted to our hospital due to acute cerebral infarction associated with a cardiac calcified amorphous tumor (CAT). The patient presented with recurrent episodes of syncope and retrograde amnesia. Brain MRI identified multiple acute cerebral infarctions, while transthoracic echocardiography (TTE) revealed a 2.5 cm echogenic mobile mass attached to the ventricular side of the posterior mitral leaflet. The patient underwent surgical resection of the mass. Pathological examination confirmed the diagnosis of a CAT. A chest computed tomography (CT), performed incidentally for pneumonia 6 months prior, revealed extensive calcifications in the mass. Postinfarction imaging showed a reduction in calcifications within the mass, suggesting a potential link between the infarction and changes in the cardiac lesion.
我们报告了一例62岁长期接受血液透析的男性患者，该患者因与心脏钙化无定形肿瘤（CAT）相关的急性脑梗死入住我院。患者表现为反复晕厥和逆行性失忆。脑部磁共振成像（MRI）发现多处急性脑梗死，而经胸超声心动图（TTE）显示一个2.5厘米的回声可移动团块附着于二尖瓣后叶心室侧。患者接受了该团块的手术切除。病理检查确诊为CAT。6个月前因肺炎偶然进行的胸部计算机断层扫描（CT）显示该团块有广泛钙化。梗死后期成像显示团块内钙化减少，提示梗死与心脏病变变化之间可能存在联系。
