Primary giant cardiac lymphoma occupying right atrium.

摘要

A 78-year-old man was admitted with dyspnea and cyanosis. Chest radiography showed severe cardiome-galy. Echocardiography (Figure 1-1) revealed a large tumor in the right atrium, extending into the right ventricle, and associated with massive pericardial effusion. Right atrial angiography showed a mass obstructing intraatrial blood flow into the right ventricle. Coronary angiography demonstrated total occlusion of the mid-portion of the right coronary artery with good distal collateral flow from a normal left coronary artery. Emergency surgery was required on the day of admission. Cardiopulmonary bypass was established with venous cannulation via the femoral vein because of the large right atrial tumor. Copious blood was observed in the pericardial cavity.
