Myxomas, metastatic tumors, thrombi, and vegetations top the differential diagnosis list of cardiac masses. We present a case of ectopic liver tissue, a far less common etiology of a right atrial mass, discovered incidentally on transthoracic echocardiography (TTE) of a 37-year-old female with multiple comorbidities who was referred to our facility for further management of left popliteal artery occlusion and right lower extremity cellulitis. We discuss further the categories, proposed pathogenesis, diagnostic approach, and potential complications of ectopic liver tissue.
