Uterine intravenous leiomyomatosis should be considered in the differential diagnosis of a right atrial mass in middle-aged women, especially those with a history of leiomyoma, hysterectomy, or myomectomy.
We report a 54-year-old female with recently diagnosed multiple cardiac thrombi and pulmonary embolism that was treated with thrombolytics and anticoagulants. She presented again with worsening dyspnea and was found to have persistent large cardiac thrombi on echocardiogram. Surgical findings revealed a single right atrial mass originating from inferior vena cava and extending into the pulmonary artery. The mass was successfully removed. Final pathology revealed a benign smooth muscle and vascular mass with estrogen and progesterone receptor positivity favoring uterine intravenous leiomyoma. She was discharged on warfarin and leuprolide therapy. This diagnosis requires a high index of suspicion, especially in a middle-aged woman with right atrial mass and history of an existing leiomyoma, hysterectomy or myomectomy.
