Metastasis: Arterially Enhancing Liver Lesion
Cancers are sorted by a combination of rarity, overall frequency of metastases, and predilection for this site.
|Hepatocellular Carcinoma||(Primary Tumor)||HCC lesions are arterially enhancing (versus normal liver or regenerating nodules, which enhance with the portal venous phase). The display wash-out, i.e. decreased enhancement compared to liver on PV phase.|
|Renal Cell Carcinoma||Uncommon|
|Pancreatic Neuroendocrine||Common||overall, a very common site for metastasis (seen in about half of all pancreatic neuroendocrine tumors). However it is almost never seen from insulinomas and uncommon in VIPoma and gastrinoma.|
|Gastrointestinal Carcinoid||Common||most common distant site. Metastases will be hyperenhancing in the arterial phase, although they may become isointense to liver on later phases.|
