Echocardiograms of three patients with metastatic carcinoma or lymphoma showed a sonolucent space posterior to the left ventricular epicardium, as seen in pericardial effusion. However, at surgery or autopsy no pericardial fluid was found. Instead, the pericardium was infiltrated by neoplastic tissue or fibrosis. In view of this finding, we suggest caution in the interpretation of "positive" echocardiograms for pericardial effusion in patients with neoplastic disease, especially if pericardiocentesis is being considered.
三名转移性癌或淋巴瘤患者的超声心动图显示，左心室心外膜后方有一个无回声区，就像心包积液时看到的那样。然而，在手术或尸检时未发现心包积液。相反，心包被肿瘤组织或纤维化浸润。鉴于这一发现，我们建议在解释肿瘤疾病患者心包积液的“阳性”超声心动图时要谨慎，尤其是在考虑进行心包穿刺术时。
