Intimal sarcoma of the inferior vena cava with extension to the right atrium.

A 65-year-old woman was treated for deep vein thrombosis with extension into the inferior cava vein for 18 months. In a magnetic resonance angiography followup study, extensive tumor growth was noted, starting below the renal veins and extending into the right atrium (Figure 1). A transjugular biopsy revealed an intimal sarcoma with no therapeutic option of radiation or chemotherapy. Because of the risk of the tumor prolapsing into the right ventricle, and after an interdisciplinary conference, it was decided to resect the tumor using a multidisciplinary team approach
