摘要

這篇文章描述一個極為罕見之案例：一位71歲女性心臟超音波顯示一1.6×2.9公分鈣化之左心房腫瘤，接受開刀後診斷出無臨床症狀之鈣化無定形心臟腫瘤。鈣化無定形心臟腫瘤是非常罕見之良性心臟腫瘤，往往被誤診為黏液瘤，並且也會由於鈣化的片段或栓塞導致相關症狀。多數個案也許是無症狀的，而偶然被診斷出來，這可以解釋僅有極少數這樣的病例報告。一般接受完全外科切除後鈣化無定形心臟腫瘤的臨床癒後是相當良好的。由於從術前的臨床影像檢驗來事先診斷幾乎不可能，因此在外科切除以後的組織病理確認是唯一的確診方式。

This article describes an unusual case of a cardiac mass, a cardiac calcified amorphous tumor (CAT), in a 71-year-old woman who presented without clinical symptoms. Echocardiography revealed a calcified left atrial mass (about 1.6 x 2.9cm). The patient received cardiac exploration and removal of the mass, and had an uneventful postoperative course. CAT is a very rare benign cardiac mass that is usually mistaken for malignancy or myxoma and may cause related symptoms due to obstruction or embolization of calcified fragments. Most patients are asymptomatic and are diagnosed accidentally, which may explain why only a few such cases have been reported in the current literature. The clinical outcome of CAT is excellent following complete surgical removal. Clinical differentiation from other cardiac masses through image study is impossible in most cases. Histopathological examination after surgical excision is the only modality for confirmation.
