How is hepatic adenoma diagnosed?

If your doctor thinks you may have a liver tumor, you’ll get an imaging test, such as an ultrasound. If the scans show that you have a tumor, you’ll likely get another imaging test that can show more detail, such as an MRI or a CT scan. This helps your doctor confirm that it’s a hepatic adenoma.

What is hepatic adenomas of the liver?

Hepatic adenomas, also referred to as hepatocellular adenomas, are benign, generally hormone-induced, liver tumors. The tumors are usually solitary, have a predilection for hemorrhage, and must be differentiated from other focal liver lesions.

What are the types of hepatic adenoma?

Inflammatory hepatic adenoma is the most common type. It’s seen in about 40 to 50 percent of cases. HNF1A-mutated type is seen in approximately 30 to 40 percent of cases….What are the types of hepatic adenoma?

• inflammatory.
• HNF1A-mutated.
• β-catenin activated.
• unclassified.

Does hepatic adenoma have central scar?

Hepatic adenomas, unlike FNH, do not have a central scar. If a low signal intensity scar is seen on T1-weighted images and the scar enhances after gadolinium is administered, the diagnosis of FNH is strongly favored. A central scar has never been reported in a hepatic adenoma.

Do liver adenomas need to be removed?

Hepatic adenomas are benign tumors that start from the main type of liver cells. Most do not cause symptoms and do not need treatment. But if they cause stomach pain, a mass in the belly, or blood loss, they may need to be removed.

How common are hepatic adenomas?

Hepatocellular adenomas (HCAs) are also known as hepatic adenomas, telangiectatic focal nodular hyperplasia (FNH) or, less commonly, liver cell adenomas. They are rare, benign tumors of epithelial origin and occur in less than 0.007-0.012% of the population.

How common is hepatic adenoma?

What causes hepatic adenomas to rupture?

HA is strongly associated with exposure to estrogens, particularly estrogen-containing oral contraceptives (OCs) [1]. Overall, up to 30% of HA tumors are associated with rupture or hemorrhage, and this risk is highest in patients with hormone use and in patients with larger tumors (>5 cm) [2].

Can hepatic adenomas shrink?

The size of hepatocellular adenoma tumors shrinks after menopause in women aged older than 50 years, according to recent findings published in Clinical Gastroenterology and Hepatology. These results suggest that women with small hepatocellular adenoma tumors who experience menopause do not have to remain in follow-up.

Do hepatic adenomas shrink?

When do you resect hepatic adenoma?

Liver resection is recommended in all male patients, irrespective of the HA size. In women, the first step is lifestyle change and re-evaluation after 6 months. If the HA increases in size or is stable and >5 cm, resection is indicated. If not (HA regression or stable and <5 cm), follow-up is adequate.
