Liver Metastases

 

General Considerations

  • In this country, a focal liver lesion is less likely to represent a primary malignancy than a metastasis
  • Metastasis is the most common neoplasm in an adult liver
    • Only lymph nodes harbor more metastatic deposits than the liver
  • The liver is a principle target for gastrointestinal malignancies
  • The most common primary sites for metastatic lesions to the liver in adults are:
    • Colon
    • Stomach
    • Pancreas
    • Breast
    • Lung
