Abstract
We have experienced a case of leiomyosarcoma of the inferior vena cava (IVC). A 45-year-old woman was admitted to the hospital because of abdominal pain localized in the right lateral region. An 8cm-sized tumor was palpable in the right upper quadrant. Abdominal ultrasonography, CT scan and magnetic resonance imaging showed the tumor in the IVC. Venography revealed a 10cm-sized filling defect of contrast a material. The IVC was obstructed and there were collateral vessels. Primary tumor of the IVC was diagnosed. The tumor, IVC and right kidney were resected en bloc. The stump of IVC was closed with the patch of Gore-Tex. The stump of iliac vein was sutured directly. Histologic analysis revealed leiomyosarcoma of the IVC. Liver metastasis was recognized 4 months after the operation and local reccurence occurred 8 months after the operation. She died 18 months after the operation.
