Objective: The aim of this report is to highlight the importance of a comprehensive preoperative evaluation in the case of intravenous leiomyomatosis.
Case Report: A 49-year-old women was presented with dyspnea and abdominal distension. Imaging studies revealed a large leiomyoma with intravenous leiomyomatosis from this mass to the right parauterine veins, right ovarian vein reaching the inferior vena cava. Complete resection was performed by a two-stage operation by a multidisciplinary team. Final pathology confirmed it to be intravenous leiomyomatosis and uterine leiomyomas.
Conclusion: Intravenous leiomyomatosis is a benign and rare disease that can be a fatal condition. Precise diagnosis and appropriate treatment are important for the best outcome. Gynecologists should consider this rare disease when a patient with a uterine tumor shows symptoms such as chest pain and dyspnea.
