A primary left atrial leiomyosarcoma mimicking myxoma: Echocardiographic findings

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. Mini-Abstract We present a case of primary left atrial leiomyosarcoma masquerading as myxoma preoperatively and discuss the echocardiographic features of hemodynamic consequences, mobility, consistency and base of the tumor. And this case report reviewed the trasesophageal echocardiography and CT findings suggesting malignancy. Finally, we emphasizes the necessity of multimodality images for the more accurate diagnosis.
