We present a case of 67\u2010year\u2010old man, who was evaluated for suspected left atria myxoma. Transesophageal echocardiography revealed a heterogeneous density originating from left atrial appendage, thought to be most consistent with a myxoma. Cardiac magnetic resonance imaging, uncharacteristically, gave an equivocal picture, suggesting the mass to be a myxoma on initial imaging and a thrombus with evidence of liquefaction necrosis following postcontrast enhancement. Surprisingly, histopathology of the mass following its surgical excision yielded a rare diagnosis of myxofibrosarcoma.<\/jats:p>","DOI":"10.1111\/echo.13790","type":"journal-article","created":{"date-parts":[[2017,12,27]],"date-time":"2017-12-27T11:04:48Z","timestamp":1514372688000},"page":"278-281","source":"Crossref","is-referenced-by-count":2,"title":["Left
