Inferior vena cava thrombosis (IVCT) is a rare complication of deep vein thrombosis (DVT) in the legs. The etiology of IVC thrombosis can be divided into genetic versus nongenetic (environmental/acquired) etiological factors found in Virchow's triad of stasis, endothelial injury, and hypercoagulability. Hyperhomocysteinemia is a rare risk factor for venous thromboembolism and atherosclerotic disease. Hence, very few cases have been described to date to knowledge. A case of a 78‐year‐old hypertensive man who presented with hyperhomocysteinemia‐induced DVT of the left leg extending toward an anatomically normal IVC is discussed in the report.
