Pedicled mobile thrombus in the right atrium is an extremely rare condition. Here, we described a case of a 42-year-old male hospitalized with complaints of chest pain and hemoptysis. Computed tomographic angiography of the pulmonary artery showed signs of embolism, and thoracic echocardiography indicated a pedicled mobile cloudy echo in the right atrium, which was initially suspected to be a myxoma. However, it was confirmed to be a thrombus by histopathological examination. Postoperatively, the patient was treated with anticoagulant therapy comprising of low molecular heparin and warfarin, and the patient recovered well. Thoracic echocardiography performed 3 months after surgery ruled out any recurrence of right atrial thrombus.References
