Objective Intravenous leiomyomatosis (IVL) invasion of the inferior vena cava is a rare disease, and there are no guidelines for the diagnosis and treatment of this disease. This study reported the diagnosis and treatment process of a case of IVL invading the inferior vena cava, which provides clinical reference experience for the diagnosis and treatment of IVL. Methods A 59-year-old woman, because of “physical examination found inferior vena cava thrombosis one month,” was admitted to hospital 4 years before left ovarian + right fallopian tube + myomectomy after admission line chest and abdominal enhanced computed tomography prompt: inferior vena cava vein (renal vein level) filling defect, the following lumen and branches without being visible, considering thrombus or tumor thrombus formation, the cervix left visible, about 8-cm-diameter fat density mass, enhanced scanning period is not strengthening. A multidisciplinary team performed laparotomy + resection of intravena cava tumor + total hysterectomy + right oophorectomy + repair of inferior vena cava and left iliac vein. Postoperative pathology suggested spindle cell tumor, leiomyomatosis. Results IVL is a special type of benign tumor in the mesoderm lobe. Surgical resection is the main mode of treatment. Conclusion Intravenous vascular leiomyoma onset is insidious, lacks clinical manifestations of specificity, and is easy to misdiagnosis and miss diagnosis. Accurate preoperative evaluation, multidisciplinary team cooper...
