BACKGROUND: Cardiac calcified amorphous tumors (CAT) are rarely presented and featured as calcification and eosinophilic amorphous material in dense collagenous fibrous tissue.

CASE REPORT: Our case report describes a 47-year-old man presenting cardiac CAT with only chronic cough and occasional dizziness. Preoperative multi-modality imaging was used to evaluate it and postoperative histological study was used to confirm the diagnosis. The mass was resected and the patient was fully recovered and discharged on the 7th postoperative day. In the 1-year follow-up, transthoracic echography showed no further pathological changes.

CONCLUSIONS: Cardiac CAT is a non-neoplastic cardiac tumor of unknown etiology. The tumor is commonly an incidental finding and the treatment of choice is complete surgical resection. In this case, we found that that multi-modality images were helpful in evaluating and diagnosing the cardiac CAT.
