Two-dimensional echocardiographic (2DE) findings in four patients with predominantly noneffusive manifestations of intrathoracic neoplasms are presented. In cases Nos. 1 and 2 tumor masses were identified in the left atrioventricular groove area at a time when the left-heart border was obscured by a large pleural effusion on chest x-ray examination. Case No. 3 demonstrated distortion of right ventricular anatomy by a compressing extrinsic mass lesion. In these three cases the neoplasm itself or the complicating pleural effusion provided additional echocardiographic windows for visualizing the heart. Case No. 4 demonstrated dilation of the main pulmonary artery secondary to tumor compression of the left pulmonary artery with regression of the dilation following resection. The relative applicability of 2DE and M-mode techniques and their clinical relevance in tumor patients are delineated.
本文介绍了4例主要表现为非渗出性胸内肿瘤患者的二维超声心动图（2DE）检查结果。病例1和病例2中，胸部X线检查显示大量胸腔积液使左心缘模糊不清，但二维超声心动图在左房室沟区域发现了肿瘤肿块。病例3显示右心室解剖结构因外部压迫性肿块病变而变形。在这3例病例中，肿瘤本身或并发的胸腔积液为观察心脏提供了额外的超声心动图窗。病例4显示左肺动脉受肿瘤压迫导致主肺动脉扩张，切除肿瘤后扩张消退。文中还阐述了二维超声心动图和M型技术在肿瘤患者中的相对适用性及其临床意义。
