title: Live/real time three-dimensional transthoracic echocardiographic findings in primary left atrial leiomyosarcoma.
abstract: We describe an adult patient with a primary left atrial leiomyosarcoma in whom live/real time three-dimensional transthoracic echocardiography showed echolucent areas within the mass consistent with necrosis or hemorrhage surrounded by dense band-like echo densities indicative of fibrosis or collagen giving a "doughnut" like appearance. These findings were consistent with histopathology, which showed areas of necrosis and dilated vascular channels within the fibrotic tumor. Our case further illustrates the usefulness of three-dimensional transthoracic echocardiography in characterizing the morphologic features of an intracardiac mass.
