Epithelioid hemangioendothelioma is a rare vascular sarcoma that arises from the lining (intima) of blood vessels. We report a case of a 43-year-old male patient, who presented with inferior vena cava (IVC) obstruction and acute bilateral lower extremity deep vein thrombosis. Mechanical thrombectomy was performed with an endovascular thrombectomy device, followed by stent placement in the IVC. The initial pathology on the retrieved specimen obtained from the thrombectomy device revealed an undifferentiated neoplasm, and definitive surgical resection of the retroperitoneal soft tissue tumor of the IVC documented a rare case of epithelioid hemangioendothelioma.
