Primary cardiac lymphoma (PCL) is a rare entity that commonly presents as a heart rhythm disorder. We describe a previously healthy, immunocompetent patient presenting with complete atrioventricular block (AVB). The patient was found to have a cardiac mass on magnetic resonance imaging and underwent percutaneous biopsy eventually diagnosing PCL. After pacemaker implantation, the patient's tumor responded rapidly to chemotherapy and the AVB completely resolved. In otherwise healthy patients presenting with AV block, cardiac tumor should be considered. Additionally, if PCL is diagnosed and the patient is clinically stable with AVB, it may be reasonable to delay pacemaker implantation until the clinical response to chemotherapy is evaluated.
原发性心脏淋巴瘤(PCL)是一种罕见疾病,通常表现为心律失常。我们描述了一例既往健康、免疫功能正常的患者,其表现为完全性房室传导阻滞(AVB)。该患者的磁共振成像检查发现心脏有肿块,并进行了经皮活检,最终诊断为 PCL。在植入起搏器后,患者的肿瘤对化疗反应迅速,AVB 完全缓解。对于其他健康状况良好、出现 AV 阻滞的患者,应考虑心脏肿瘤的可能。此外,如果诊断为 PCL 且患者的 AVB 临床表现稳定,在评估化疗的临床反应后再决定是否植入起搏器可能是合理的。
