Cardiac lymphoma requiring surgical resection

[摘要] A 62-year-old woman was admitted to the emergency departmentwith fever, cough, dyspnea, and weight loss of 5 kg in 6 months. Computed tomography revealed numerous lung nodules, masses in bothbreasts, multiple enlarged lymph nodes, and large low-density areasin the right atrium. Transthoracic echocardiography showed a 35-mmhypoechoic mass in the right atrium, extending like a stalk from nearthe superior vena cava (SVC), which moved significantly with the heartbeat (Figure 1). Breast biopsy revealed a diffuse large B-cell lymphoma (DLBCL). Intracardiac tumor resection was performed beforechemotherapy to prevent tumor embolism or valvular obstruction.The surgery was performed through a midline sternal incision. Whenthe right atrium was incised with extension in the SVC direction, theinside of the right atrium was filled with a tumor with good mobility (Figure 2). The tumor was firmly adherent near the junction of theright atrium and the SVC.
