Pearls and Pitfalls
Currently, most liver masses are asymptomatic and are identified incidentally during survey for chronic liver diseases or other purposes.
Many liver masses occur in cirrhotic livers secondary to chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections.
Abdominal ultrasonography is the most convenient imaging modality to screen patients at risk for liver masses and will differentiate cystic from solid tumors.
Dynamic computed tomography (CT) is recommended to assess the liver tumor and remainder of the abdominal cavity simultaneously.
CT, magnetic resonance imaging (MRI), and angiography can be valuable and complementary in the evaluation of liver masses.
Tumor markers, such as α-fetoprotein (AFP), carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA19-9), may help to narrow the differential diagnosis.
Positron emission tomography (PET) has not proven useful or cost-effective for differentiating most liver masses.
Liver biopsy is...
