After an attack of pleuropneumonia a 25-year-old woman developed persistent dyspnoea due to pulmonary emboli, as demonstrated by scintigraphy. There was no clinical or phlebographic evidence of the peripheral venous system as the source. Two-dimensional echocardiography demonstrated a floating spherical tumour in the right atrium, attached to the interatrial septum and prolapsing into the right ventricle during ventricular diastole. Because of the risk of further thromboembolic episodes the tumour was removed operatively without any complication. It proved to be myxoma-like, 3 x 3 cm in diameter. Histologically it was a thrombus without evidence of myxoma. No further thromboemboli occurred under phenprocoumon anticoagulation.
一名25岁女性在患胸膜肺炎后，因肺栓塞出现持续性呼吸困难，闪烁扫描证实了这一情况。没有临床或静脉造影证据表明外周静脉系统是栓子来源。二维超声心动图显示右心房有一个漂浮的球形肿瘤，附着于房间隔，在心室舒张期脱垂入右心室。由于有进一步血栓栓塞发作的风险，该肿瘤被手术切除，无任何并发症。它直径为3×3厘米，类似黏液瘤。组织学检查显示为血栓，无黏液瘤证据。在苯丙香豆素抗凝治疗下未再发生血栓栓塞。
