Diagnosis With Brief Discussion

Diagnosis
Metastasis of Hepatocellular Carcinoma to Inferior Vena Cava through Inferior Phrenic Vein
Radiologic Findings
Mediastinal windows of enhanced chest CT show low attenuated filling defect in the IVC, inferior phrenic vein and right atrium. Liver dynamic CT show lower attenuated mass with enhancement in the right anterior segment of liver. Surgical en-block resection of tumor thrombi in the IVC and right atrium was performed.
Brief Review
The incidence of portal vein and/or inferior vena cava tumor thrombi is higher in patients with hepatocellular carcinoma (HCC). It has been reported in as many as 44?84% of these patients in autopsy data. It has also been estimated, from clinical data, that the incidence of HCC thrombosis ranges between 34% and 50%. Most of these patients have a poorer prognosis; their duration of survival is only 2.4?2.7 months without treatment. The inferior phrenic vein (IPV) is one of the major sources of collateral venous drainage in HCC. Additional venous drainage provided by the IPVs could serve as a possible route of metastasis through the diaphragm and into the thoracic cavity. This case show IVC and right atrium metastasis through right inferior phrenic vein.
