Echocardiography is the initial imaging modality to delineate the cardiac mass. Clinically echocardiographic information about morphology, location, motion and hemodynamic consequences of the tumor is very important for decision making in terms of additional imaging studies and treatment. We present a case of left atrial leiomyosarcoma masquerading as myxoma preoperatively and discuss the echocardiographic features for distinguishing leiomyosarcoma from a benign tumor, such as myxoma.
