A Case of Cardiac Lymphatic Malformation Found Incidentally

Abstract

We herein report an extremely rare cardiac tumor of lymphatic malformation in 77-year-old man. The computed tomography (CT) demonstrated a mass from the lateral side of the left atrium to the lateral and posterior wall of the left ventricle among intrapericardial adipose tissue involving the left coronary artery. We performed partial resection of the tumor for definitive diagnosis under cardiopulmonary bypass. The histological finding was cardiac lymphatic malformation and was considered to be benign. There was no evidence of the growth of any cardiac tumor during the one-year follow up.
