Case report reveals massive postoperative pulmonary embolism following resection of intracardiac intravenous leiomyomatosis, highlighting the necessity of multidisciplinary management.
Intravenous leiomyomatosis (IVL) is a rare subtype of benign smooth muscle tumor that can exhibit malignant-like biological behavior. Originating in the uterus, IVL grows in mass-like formations within small veins and can extend into the inferior vena cava (IVC), right atrium, and pulmonary arteries. Due to the potential for life-threatening consequences when IVL invades the heart and pulmonary arteries, early diagnosis and radical resection through a multidisciplinary approach are crucial. This report presents a case of uterine intravenous leiomyomatosis involving the IVC and right atrium, complicated by massive pulmonary embolism after surgery, and includes a literature review to discuss the clinical implications.
