A Case of Recurrent Tumor Thrombi in the Inferior Vena Cava after Resection for Sigmoid Colon Carcinoma with Multiple Liver Metastases

Isolated hepatic metastasis with hepatic venous invasion and tumor thrombus in right atrium

“…There are very few reports in the literature on liver metastasis associated with hepatic venous invasion either with or without formation of tumor thrombosis in the right atrium.
