Combined transthoracic echocardiography and contrast‐enhanced ultrasonography to trace intravenous leiomyomatosis with intracardiac extension

Intravenous leiomyomatosis (IVL) with intracardiac extension is a rare condition, which the benign tumor invades into the right heart through inferior vena cava. We described the findings of ultrasonography in eight patients with this disease. Transthoracic echocardiography (TTE) can reveal the intracardiac lesion burden and associated compromise. Contrast‐enhanced ultrasonography (CEUS) can trace the origin of the lesion and extension. Therefore, combining TTE with CEUS is used to better characterize this complex lesion and plays a crucial role in guidance of surgical decision.
