A large intrapericardial cyst presenting as a cardiac abnormality.
A case of mitral regurgitation apparently caused by extrinsic pressure of the large intrapericardial cyst distorting the mitral valve is reported. The initial radiographic appearance of the cyst suggested an atypically enlarged left atrium. The mitral regurgitation subsided after surgical drainage of the cyst. The angiogram showed elevation of the right pulmonary artery and depression of the left atrium.
