A case is described of a 57-year-old man with a background of low-grade bronchus-associated lymphoid tissue (BALT) non-Hodgkin's lymphoma presenting with dyspnoea and palpitations. Diagnostic work-up revealed paroxysmal atrial flutter and the presence of a mass in the right lower lobe at bronchoscopy, with histology confirming recurrent BALTOMA. Transthoracic echocardiography (TTE) revealed a mass in the right atrium. Transoesophageal echocardiography (TOE) confirmed the presence of a fleshy, mobile pedunculated right atrial mass adherent to the interatrial septum, with features more in keeping with an atrial myxoma rather than intracardiac lymphoma. He proceeded to cardiotomy and excision of the mass with histology confirming an atrial myxoma. The clinical and echocardiographic features of atrial myxomas and intracardiac lymphomas are briefly discussed.
本文描述了一例57岁男性患者，有低度支气管相关淋巴组织（BALT）非霍奇金淋巴瘤病史，表现为呼吸困难和心悸。诊断检查发现阵发性心房扑动，支气管镜检查显示右下叶有一肿块，组织学检查证实为复发性BALTOMA。经胸超声心动图（TTE）显示右心房有一肿块。经食管超声心动图（TOE）证实右心房有一个肉质、可移动的带蒂肿块附着于房间隔，其特征更符合心房黏液瘤而非心内淋巴瘤。患者接受了心脏切开术并切除肿块，组织学检查证实为心房黏液瘤。本文简要讨论了心房黏液瘤和心内淋巴瘤的临床及超声心动图特征。
