An 89-year-old woman with chronic atrial fibrillation, hypertension, chronic heart failure, and dementia was admitted to our hospital due to multiple small cerebral and cerebellar infarctions. Transthoracic echocardiogram revealed a floating calcified mass lesion arising from the endocardium of the posterior portion of the mitral annulus with mitral annular calcification. Furthermore, the mass had a heterogeneity of the echogenicity. The mass was diagnosed as a calcified amorphous tumor based on specific echocardiographic features. Serial echocardiograms showed shrinkage and disappearance of the mass, and magnetic resonance image revealed new infarction in the left occipital lobe. Embolization of the mass appeared to cause systemic embolism.
一名89岁女性，患有慢性心房颤动、高血压、慢性心力衰竭和痴呆症，因多发性小的脑和小脑梗死入住我院。经胸超声心动图显示二尖瓣环后部心内膜出现一个漂浮的钙化肿块病变，伴有二尖瓣环钙化。此外，该肿块的回声不均匀。根据特定的超声心动图特征，该肿块被诊断为钙化性无定形肿瘤。系列超声心动图显示肿块缩小并消失，磁共振成像显示左枕叶出现新的梗死灶。肿块的栓塞似乎导致了全身性栓塞。
