Giant primary cardiac liposarcoma vascularized via the circumflex coronary artery.
A 51-year-old patient presented with a history of chest pain and progressive dyspnea. CT scan demonstrated a lipomatous mass encircling the heart and compressing the left lung. After median sternotomy, an intrapericardial tumor of 3200 g with a vascular pedicle arising from the circumflex coronary artery was resected. A histologic diagnosis of a well-differentiated liposarcoma was made. The patient is alive and well 2 years postoperatively. This tumor with its unusual vascularization is the largest of the few primary cardiac liposarcomas that have been reported.
