[Cadiac lipoma of the right atrium;report of a case].

Cardiac lipoma is a rare benign tumor. A 42-year-old male was referred to our hospital to undergo thorough examination and treatment of a space-occupying right atrial lesion, detected incidentally by chest computed tomography(CT). After admission, it was diagnosed as cardiac lipoma by echocardiography, CT, and magnetic resonance imaging. We resected the tumor under cardiopulmonary bypass and reconstructed the right atrium using a bovine pericardial patch. The histopathological examination reveaed that the tumor was lipoma. The postoperative course has been uneventful without recurrence for nearly 2 years.
