Intravenous Leiomyomatosis of the Uterus: A Retrospective Single-Center Study in 14 Cases

Figure 7

Case 6. (a) CT shows that the tumor enters the inferior vena cava from the right iliac vein and bilateral ovarian veins (arrows). The tumor in the right ovarian vein directly enters the inferior vena cava, and the tumor in the left ovarian vein enters the inferior vena cava via the left renal vein. (b1) and (b2) are the same image. (b1) shows that the main pulmonary artery and the superior vena cava are unobstructed under conventional CT brightness. (b2) can show the low-density shadow in the main pulmonary artery and the superior vena cava after adjusting the contrast (arrow). (c1) and (c2) were the same image in the arterial phase. The arrow of (c1) showed left inferior pulmonary artery embolism, and no obvious abnormalities were found in the right atrium and right ventricle. Low-density shadows in the right atrium and right ventricle were faintly visible after adjusting the contrast of (c2) (arrow). (d) The venous stage. The right atrium and right ventricular tumor can be faintly seen. (e) Cardiac ultrasound showed right atrium and right ventricular tumor with unclear boundary, (f) echocardiography shows intrapulmonary tumors. (g) A part of the removed tumor specimens, with irregular pattern (cauliflower-like), brittle texture, and easy fracture.
