Surgical resection removes a cardiac calcified amorphous tumor linked to cerebral infarctions in a hemodialysis patient.
Case Report (n=1)
Cardiac calcified amorphous tumors can be a potential source of cerebral infarction, highlighting the importance of echocardiographic evaluation in patients with stroke.
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.

Kim et al. (2025) conducted a case report in Acute cerebral infarction associated with a cardiac calcified amorphous tumor (n=1). Cardiac calcified amorphous tumor (CAT) was evaluated. A cardiac calcified amorphous tumor in a 62-year-old hemodialysis patient was identified as a potential cause of multiple acute cerebral infarctions and was treated with surgical resection.
