Unlike the most common liver mass which is the hemangioma, focal nodular hyperplasia is thought to be the result of increased hepatocyte number caused by hypoperfusion or hyperperfusion from anomalous arteries within the hepatic lobule.

What causes FNH of liver?
FNH most probably arises as a reaction to local hemodynamic instability in the liver. The generally accepted theory on the genesis of FNH lesions is that arterial malformations disturb the local blood flow, thus causing a hyperplastic response of normal liver cells to either hyperperfusion or hypoxia [1].
Is FNH serious?
FNH is a benign tumor, or lesion, that forms in the liver. These tumors are not cancer. FNH is more common in women, mostly between the ages of 20 and 50. It's the 2nd most common type of benign liver tumor (liver hemangiomas are the most common).
Is FNH considered a liver disease?
Focal nodular hyperplasia (FNH) is a rare benign disease of the liver and the second most common benign lesion in healthy, young and middle-aged women (1-4). The pathogenesis of this disease is unclear (5,6). Most researchers think that it is a reactive process of the liver to vascular damage or deformity.
Focal Nodular Hyperplasia
What causes focal nodular hyperplasia liver?
Unlike the most common liver mass which is the hemangioma, focal nodular hyperplasia is thought to be the result of increased hepatocyte number caused by hypoperfusion or hyperperfusion from anomalous arteries within the hepatic lobule.
What causes FNH of the liver?
FNH most probably arises as a reaction to local hemodynamic instability in the liver. The generally accepted theory on the genesis of FNH lesions is that arterial malformations disturb the local blood flow, thus causing a hyperplastic response of normal liver cells to either hyperperfusion or hypoxia [1].
How do you treat focal nodular hyperplasia?
If the FNH is large, surgeons may remove the tumor. In partial hepatectomy surgery, or resection, surgeons extract the tumor and a small part of the tissue around it.

Is focal nodular hyperplasia considered liver disease?
Focal nodular hyperplasia (FNH) is a rare benign disease of the liver and the second most common benign lesion in healthy, young and middle-aged women (1-4). The pathogenesis of this disease is unclear (5,6). Most researchers think that it is a reactive process of the liver to vascular damage or deformity.
Does FNH go away?
With the increasing use and improvement of diagnostic imaging, FNH is being observed more often. It has been shown, using radiological approaches, that most FNH remain stable, or even regress, over a long follow-up period. In addition, it is extremely rare that FNH were discovered in elderly.
Focal Nodular Hyperplasia
Does focal nodular hyperplasia need follow up?
Conclusion. Although a well-established diagnosis of FNH usually requires no treatment or surveillance, careful examination remains necessary when the FNH is large and projects from the liver because of the possibility of rupture and hemorrhage.
Should FNH be removed?
Thus FNH is often found incidentally on health screening. If symptoms are present, appropriate conservative treatment should be performed. Surgical resection can be considered if symptoms persist or if imaging findings are difficult to distinguish from other diseases requiring surgical treatment.
