Cardiac Calcified Amorphous Tumor Presenting as Cerebral Infarction

Abstract

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 8 mm 5 mm 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.

Cerebral Embolism Associated with Calcified Amorphous Tumor: A Review of Cerebral Infarction Cases

“…Although there were more women than men in all previous reports on CAT ( 1 , 4 , 11 , 19 ), there was no marked difference between sexes in the CAT-induced CI cases (nine men and nine women). This discrepancy in findings may be due to gender differences in incidence and the small number of cases with CI morbidity, but the truth of the matter is unclear.…”

“…We reviewed all previous cases of CAT-induced CI and found 17 reported cases ( 1 , 5 - 19 ) ( Table ). First, we performed a PubMed search of all available literature from January 1, 1997, to July 31, 2020, using the terms “calcified amorphous tumor.” A total of 68 articles were found.…”
