Hepatic fnh is a focal nodular hyperplasia, a benign disease that is rare, usually asymptomatic, with a good prognosis and a low chance of malignancy. The common treatment is observation and follow-up, with surgery if necessary. Hepatic fnh is a localized focal nodular hyperplasia of the liver caused by vascular hyperplasia and inflammation due to congenital arteriovenous malformations of the liver, resulting in impaired blood flow to the liver. The clinical manifestations of the disease are inconspicuous, and it does not affect the normal life of the patient, but in some cases, a mass may be detected in the right epigastric region of the patient. Currently, the treatment of hepatic fnh consists of regular observation and follow-up. Surgery is usually not necessary, but patients with large size and localized compression of the liver may require surgery or radiofrequency ablation. The treatment of hepatic fnh should be individualized under the guidance of a doctor, and the patient should undergo relevant examinations and actively cooperate with the doctor.
