We present a case of a 56-year-old woman with abdominal pain, normal laboratorial exams, normal carcinoembryonary antigen (CEA) and abdominal tomography exam with tumor formation in hepatic region. A tumor lesion was identified in a surgery in the medial segment of the inferior vena cava. A surgical resection was done, respecting the security limits, and reconstruction of the inferior vein with polytetrafluoroethylene (PTFE) graft was performed. The histological examination showed differentiated leiomyossarcoma of the inferior vena cava. This report points to the necessity of differential diagnoses with leiomyossarcoma in the presence of abdominal mass, supra-mesocolic, and non-specific abdominal symptoms, since its pre-surgical diagnoses occurs in only 5% to 10% of the cases.
