Abstract

We report a case of a cardiac lipoma arising from the free wall of right atrium, which was diagnosed as the presumed source of angina by compressing the right coronary artery in a 54-year-old woman. Surgical excision of the tumor was performed well. She continues to do well for six months without angina.

Figure

• 

  Fig. 1 Echocardiography demonstrates an intracardiac mass broadly attached to the free wall of right atrium without causing obstruction or regurgitation of tricuspid valve. A: Transthoracic echocardograhic view. B: Transesophageal echocardiographic view.

• 

  Fig. 2 Chest computed tomography also shows right atrial intracardiac mass with the same density as subcutaneous fat layer, suggesting a high likelihood of lipoma.

• 

  Fig. 3 A: Coronary angiography reveals no significant fixed or dynamic stenosis. B: Right atriogram shows a round well-demarcated, redundant mass in the right atrium.

• 

  Fig. 4 Histology demonstrates that a yellow well-capsulated mass is consistent with lipoma.
