RESUMO
Intravenous leiomyoma is a rare condition that occurs when there is a vascular invasion of a pre-existing uterine leiomyoma. The tumor can metastasize to structures such as the heart and lungs. We discuss a case of metastasis to the heart resulting in severe tricuspid regurgitation. Surgical intervention is the primary modality; usually a staged approach involving cardiac surgery along with abdominal and/or pelvic surgery. We want to highlight the importance of fully investigating right-sided cardiac masses. While there are common etiologies for these masses, one must maintain a high degree of suspicion for an intravenous leiomyoma, especially if a female has certain risk factors such as a prior history of fibroids or a hysterectomy. We also stress the importance of a multi-disciplinary team approach when providing care to these patients, along with reviewing all modalities of imaging.
