A patient with a large tumour of the superior mediastinum, detected by routine chest X-ray examination, is presented. Compression of the heart and the superior mediastinum produced the clinical picture of cardiac tamponade and obstruction of the superior vena cava and trachea. The solid nature of the tumour was established by echocardiography which, in addition, showed: (1) posterior displacement of the heart; (2) diminished dimensions of the left atrium and left ventricle; (3) prominent respiratory variation in the position of the interventricular septum, the dimensions of both ventricles, and the duration of systolic separation of the aortic valve cusps; and (4) 'pseudo-prolapse' of the mitral valve. All abnormal clinical signs and echocardiographic findings disappeared promptly after surgical resection of the tumour which was found to be a thymoma.
本文报道了一名通过常规胸部X线检查发现患有上纵隔大肿瘤的患者。心脏和上纵隔受压导致了心脏压塞以及上腔静脉和气管梗阻的临床表现。通过超声心动图确定了肿瘤的实性性质，此外，超声心动图还显示：（1）心脏向后移位；（2）左心房和左心室尺寸减小；（3）室间隔位置、两个心室的尺寸以及主动脉瓣叶收缩期分离持续时间有明显的呼吸变化；（4）二尖瓣“假性脱垂”。手术切除肿瘤（经病理检查发现为胸腺瘤）后，所有异常临床体征和超声心动图表现迅速消失。
