The authors describe the echocardiographic features of 19 cases of intracardiac metastatic tumours diagnosed over a 5-year period. The cardiac appearances were very varied: pericardial effusion alone or associated with an intrapericardial tumour (9 cases), myocardial infiltration (9 cases), immobile or mobile intracavitary tumour sometimes simulating a myxoma (15 cases). In 18 out of the 19 cases, the tumour mass was hyperechogenic which made it easy to diagnose. However, in one case of right atrial tumour, the mass was hypoechogenic and the diagnosis could only be made by contrast echocardiography. This study illustrates the important role that two-dimensional echocardiography plays in the non-invasive diagnosis of intracardiac metastatic tumours but physicians should be aware of the potential pitfalls and limitations of the technique.
作者描述了5年间诊断出的19例心脏转移性肿瘤的超声心动图特征。心脏表现多种多样：单纯心包积液或合并心包内肿瘤（9例）、心肌浸润（9例）、固定或活动的心腔内肿瘤，有时类似黏液瘤（15例）。19例中有18例肿瘤团块回声增强，易于诊断。然而，1例右心房肿瘤团块回声减低，只能通过超声心动图造影进行诊断。本研究表明二维超声心动图在心脏转移性肿瘤的无创诊断中发挥着重要作用，但医生应意识到该技术的潜在陷阱和局限性。
