Differential Diagnosis of the Liver Mass
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
