Malignant metastases are among the most common cardiac masses. We report a rare case of cardiac involvement by Burkitt lymphoma in a 49-year-old man who presented with a 2-month history of dyspnea and palpitations. A transthoracic echocardiogram revealed 2 intracardiac masses in the right atrium (one of which partially encased the tricuspid valve), myocardial infiltration, and pericardial disease. Results of pleural fluid cytology and flow cytometry confirmed involvement by Burkitt lymphoma. Subsequent chemotherapy markedly reduced the intracardiac tumor burden and resolved the patient's presenting symptoms. Our case highlights the importance of cardiac imaging in diagnosing systemic illness, initiating early and appropriate treatment, and monitoring disease progression in patients with intracardiac Burkitt lymphoma.

恶性转移是最常见的心脏包块。我们报道了伯基特淋巴瘤在49岁男性中出现呼吸道和心pit 2个月病史的罕见案例，涉及心脏受累。经胸超声心动图检查发现右心房有2个心内包块（其中一个部分包裹了三尖瓣），心肌浸润和心包疾病。胸水细胞学和流式细胞术的结果证实了伯基特淋巴瘤的参与。随后的化疗显着减轻了心脏内肿瘤的负担，并解决了患者出现的症状。我们的病例强调了心脏成像在诊断系统性疾病，早期及适当治疗以及监测心脏内Burkitt淋巴瘤患者疾病进展中的重要性。
