ABSTRACT
Cardiac cavernous hemangioma is an extremely rare benign tumor. A 53-year-old female had undergone resection of left breast cancer 9 years before, and her clinical course had been uneventful for nearly 9 years. She then experienced sudden fatigability and palpitations. Pericardial effusion and a tumor-like lesion, pressing the right side of the heart, were detected by echocardiography, computed tomography and magnetic resonance imaging. Though her symptoms were ameliorated with pericardial puncture, she was referred to our department for a definitive diagnosis and, if indicated, tumor resection. At surgery the tumor was poorly demarcated and most of it was resected under extracorporeal circulation. The histopathological examination revealed it was cavernous hemangioma. The patient's postoperative course has been uneventful without recurrence for approximately 2 years.
