title: Unusual "Polycystic" Appearance of a Right Atrial Angiosarcoma Described by Transesophageal Echocardiography.
abstract: Angiosarcoma is the most common primary sarcoma of the heart and the most frequent location of the tumor is the right atrium. In the few published cases of right atrial angiosarcoma studied by transesophageal echocardiography, the features described greatly differ from one to another. We describe the transesophageal images of a prolapsing mass type angiosarcoma with polycystic appearance previously misinterpreted as a right atrial myxoma in two consecutives transthoracic echocardiograms.
