We present a case of a 61-year-old female diagnosed with soft-tissue fibrosarcoma of the shoulder with a right atrial mass on transthoracic echocardiogram. To further assess the mass, contrast transoesophageal echo was performed. The mass was highly considered to be a thrombus due to the presence of multiple risk factors: atrial fibrillation, catheter use, and pulmonary embolism. However, a metastatic fibrosarcoma could not be excluded, given its enhancement with echo contrast. Finally, it was proved to be a thrombus with its rapid resolution while on anticoagulation. Therefore, it should be noted that in rare circumstances, thrombus may show enhancement with echo contrast and one needs to integrate all of the patient information to arrive at the correct diagnosis.
我们报告一例61岁女性患者，经胸超声心动图检查诊断为肩部软组织纤维肉瘤，同时发现右心房有一肿块。为进一步评估该肿块，进行了经食管对比超声检查。由于存在多种危险因素：心房颤动、使用导管和肺栓塞，该肿块高度怀疑为血栓。然而，鉴于其在超声造影下有强化表现，也不能排除转移性纤维肉瘤。最终，经抗凝治疗后肿块迅速消退，证实为血栓。因此，应注意在罕见情况下，血栓在超声造影下可能会出现强化，需要综合患者所有信息才能做出正确诊断。
