One-stage resection of intravascular leiomyomatosis involving the right heart chamber through a single laparotomy

Magnetic resonance imaging findings of intravascular leiomyomatosis of the uterus: a case report

Background

Intravascular leiomyomatosis (IVL) is often a non-malignant condition that grows inside the blood vessels and does not invade surrounding tissues. However, its presence within the blood vessels can lead to obstructions. The majority of IVL cases manifest symptoms related to blockage.

Case presentation

We present a case of a 50-year-old female patient who was referred to our institution due to the presence of a common non-cancerous tumor in the uterus, known as a benign uterine leiomyoma. The tumor was identified during an ultrasound examination during a routine physical examination. Postoperative pathology established the existence of intrapelvic IVL.

Conclusion

Intrapelvic IVL often not present with complications when it is confined to the pelvic cavity. Furthermore, the imaging features of intrapelvic IVL resemble those of typical benign uterine leiomyomas. This can often result in the clinical misdiagnosis of the tumor as a typical benign uterine leiomyoma.

Update on clinical characteristics and molecular insights for uterine intravenous leiomyomatosis (Review)

Intravenous leiomyomatosis (IVL) is a rare benign disease, which typically develops along vascular vessels and extends to the inferior vena cava and right atrium of the heart. In the early stages of the disease, the clinical manifestations and the results of imaging examinations are not uniform among patients. Thus, a high rate of misdiagnosis and missed diagnosis is common. When the tumor extends along the venous system to the pelvic floor vein or through the inferior vena cava involving the right atrium of the heart or the pulmonary artery, severe symptoms occur, such as ascites, dyspnea, heart failure and even sudden mortality. Improving the understanding of IVL to identify and evaluate this disease in its early stages is important. Complete tumor resection remains the primary treatment option for IVL. The recurrence rate of the disease varies depending on multiple factors, such as type of surgical procedure performed. Therefore, long-term follow-up is necessary for patients with IVL. The review of recent findings on the molecular and clinicopathological characterization of IVL is important to understand the pathogenesis of IVL. In the present study, the clinical manifestations, pathogenesis, differential diagnosis, treatment and prognosis of IVL are summarized in order to provide a single source of insightful information on IVL.

Intravascular leiomyomatosis with cardiac and pelvic involvement in a postmenopausal woman: A case report of multidisciplinary team management

Intravascular leiomyomatosis (IVL) is a rare benign condition in which a leiomyoma, originating from the uterus, propagates through the pelvic venous system and occasionally extends into the inferior vena cava (IVC), occasionally reaching the heart. Despite its low incidence and benign nature, IVL can lead to life-threatening obstructions in the right heart's outflow tract, potentially resulting in sudden death. In this article, we present a case of a 72-year-old postmenopausal patient with IVL, who initially presented with palpitations. The diagnosis was made through echocardiography and a computerized tomography (CT) scan, revealing a tumor that extended from the uterus through the IVC and into the right ventricle. The patient was managed by a multidisciplinary team of gynecologists and cardiothoracic surgeons, who performed a single-stage surgical removal of a tumor 25 cm long. The pathological report confirmed the diagnosis of IVL. Postoperative follow-up is crucial, as IVL recurs in up to 30% of cases. This article's objective is to provide a clinical illustration of this exceedingly rare condition, with fewer than 300 reported cases, and to offer a comprehensive overview of IVL, including its clinical presentation, diagnosis, treatment, and outcomes.
