Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver. The lung and bone are the two most common sites for the metastasis of HCC. Our patient presented with rapidly growing chest wall mass that was subsequently biopsied and revealed metastatic HCC.

Typical HCC features of arterial phase enhancement with washout on portal venous phase relative to liver parenchyma apply to cirrhotic liver. In this case, decreased attenuation due to generalized hepatic steatosis means that washout cannot be assessed on CT.
