摘要：Intravenous leiomyomatosis (IVL) is a rare,histolo-gically benign uterine smooth muscle tumor with malignant biological behavior due to its propensity for intravascular extension.[1]While gynecological in ori-gin,its most severe manifestations are cardiovascular,ari-sing from tumor propagation through the venous system into the inferior vena cava (IVC),right heart,and pulmon-ary arteries,mimicking thromboembolic disease.[2,3]This can lead to pulmonary embolism (PE),right heart obst-ruction,and even sudden cardiac death.[4]Diagnosis is ch-allenging,often delayed by misdiagnosis as conventional PE. We present two cases of IVL initially presenting with PE,highlighting the critical cardiovascular implications and diagnostic pitfalls.
