Left atrial myxoma on transthoracic and transesophageal echocardiography

A four chamber view from a transthoracic echocardiography (panel A) suggests a well encapsulated mass within the left atrium (arrow). The consistence is fairly uniform although there may be a few rarefactions. Transesophageal echocardiography (panel B) shows the details of the tumor attachment to the lower limbus of the foraminal portion of the interatrial septum. The implied irregularity on transthoracic echocardiography are clearly seen cysts that are also typical of these tumors.
