<p>　症例は81歳女性．既往歴に2型糖尿病と脳梗塞がある．X年，CTで心臓腫瘍が疑われ当院受診．UCG，CT，MRIにて僧帽弁輪部から房室間溝に沿って広がる径36 mmの石灰化腫瘤がみられ，骨シンチで骨化形成反応を認めた．外科的切除は困難であった．その後腫瘤は増大し，X＋5年に僧帽弁狭窄兼閉鎖不全が出現，X＋9年に急性心不全をきたした．X＋10年，誤嚥性肺炎にて死亡．剖検にて心臓腫瘤は，60×60 mm大で表面は骨化し，乾酪変性様内容物を認めcalcified amorphous tumor（CAT）と診断された．</p><p>　CATは稀な非腫瘍性石灰化腫瘤であり，主に径20 mm以下の大きさで末期腎不全透析患者に発症する．本症例は初診時，径36 mmと大きく腎機能も正常で従来の報告と異なっており，かつ10年間進行過程を観察しえた極めて稀な症例と考えられた．</p>
