Leiomyosacroma of the inferior vena cava is an extremely rare malignancy originating from the tunica media of the venous wall. Its symptoms and radiomorphological signs do not always lead to an accurate diagnosis. Histological sampling can be dangerous due to its location. Therefore the diagnosis is often a challenge for clinicians. Its treatment is primarily surgical, supplemented by radiotherapy and chemotherapy applied together or in monotherapy. In our case, an asymptomatic 74-year-old female patient was diagnosed with a tumor of the inferior caval vein located just above the right renal vein and involving the right adrenal gland. As serum cortisol, epinephrine, norepinephrine, adrenocorticotropic hormone (ACTH), total and free testosterone, dehydroepiandrosterone sulfate (DHEA-S), sex hormone binding globulin (SHBG) was at normal level, the tumor showed no hormone secretion. Primary surgical resection was planned. Preoperative biopsy was not performed due to its high risk of complications. During operation, tumor resection was performed by resection of the venous wall, removal of the right adrenal gland and neoimplantation of the right renal vein. For better exposure, cholecystectomy was also performed at the beginning of surgery. There were no postoperative complications. The patient received adjuvant radiation therapy. Thanks to the early diagnosis of the tumor and the complete resection, we significantly increased the patient’s chances of total recovery. With the radiotherapy performed, we reduced the likelihood of tumor recurrence.
