Uterine intravenous leiomyomatosis with cardiac extension: Imaging characteristics and literature review

Figure 1 Echocardiogram of the heart and inferior vena cava. A, B: Axial image demonstrates a mass within the right atrium that moves back and forth through the tricuspid orifice into the right ventricle in the systolic and diastolic period; C: Axial image demonstrates a mass within the inferior vena cava (arrows).

Figure 2 Preoperative pelvic contrast enhanced computed tomography shows a big irregular mass exhibiting heterogeneous enhancement.

Figure 3 Preoperative chest and abdominal computed tomography. A: Axial image demonstrates a lobulated mass within the right atrium and ventricle; B: Axial image shows a tumor in the inferior vena cava and resulting lumen stenosis.

Figure 4 Coronal plane computed tomography and digital subtraction angiography image of intravenous leiomyomatosis. A: Preoperative coronal plane computed tomography demonstrates a mass was present in the left ovarian vein, left renal vein, left external and common iliac vein, as well as within the inferior vena cava, extending into the right atrium; B: Digital subtraction angiography image demonstrates an irregular mass filling defect from the inferior vena cava to the right atrium.
