Hepatic FNH refers to focal nodular hyperplasia of the liver, which is a benign occupying lesion of the liver, mainly seen in young women. The cause of focal nodular hyperplasia of the liver, which is not fully understood, may be related to congenital vascular malformations, hepatic misshapen processes, focal injuries and excessive local arterial perfusion of the liver parenchyma, however, there is no association with oral contraceptive use. The typical pathological presentation is a central stellate scar that radiates from the central area of the fibrotic axis to the periphery in the form of fibrous cords, and a central scar with proliferating bile ducts and hepatic arteries, but no portal vein. Focal nodular hyperplasia of the liver is less likely to show necrosis and hemorrhage, and is not carcinogenic. Therefore, clinically, lesions with smaller diameters can be observed with regular follow-up. In contrast, surgical treatment, mainly including regular liver segmental or lobectomy, should also be considered when the diameter exceeds 5 cm or is progressively enlarged and other malignant lesions cannot be excluded.
