Overview
Hepatocellular adenoma differential diagnosis
Radiological differential diagnosis
- Hepatocellular carcinoma (HCC)Invalid parameter in
<ref>tag
- Washout tends to leave the lesion hypointense c.f. to rest of liver
- Rim enhancement of pseudocapsule may persist on delayed scan
- Different demographics
- May be difficult to distinguish if well differentiated
- Fibrolamellar hepatocellular carcinoma
- Radiating/central scar
- Calcification more common
- Lymph node enlargement common
- Focal nodular hyperplasia (FNH)
- T2: bright central scars that have late enhancement
- US: may be difficult to differentiate adenoma from FNH on nonenhanced ultrasound
- Liver metastases (hypervascular)
- Usually hypointense on T1, and moderately hyperintense on T2
- Fat and haemorrhage are less common
- Haemangioma of the liver
