We report the case of a 62-year-old man who was admitted for acute cerebral infarction linked to a cardiac calcified amorphous tumor（CAT). The patient, who had been on hemodialysis for about 10 years, was referred to our hospital with dysarthria, and left hemiplegia. Brain magnetic resonance imaging（MRI）showed acute cerebral infarction in right parietal lobe of the cortex, and transthoracic echocardiography revealed moderate aortic valve stenosis and a mobile mass measuring 8mm×5mm in diameter attached to the aortic valve. The mobile structure was thought to be related to the cerebral infarction. Aortic valve replacement was performed. On the basis of the pathological examination, a cardiac calcified amorphous tumor was diagnosed. The patient was discharged from our hospital without any complication.
