Focal nodular hyperplasia (FNH) is generally considered a benign liver lesion, rather than a disease. It's an abnormal growth in the liver composed of healthy liver cells (hepatocytes) arranged in an unusual pattern.
Understanding FNH
FNH is characterized by:
- Hyperplastic Hepatocytes: A proliferation of normal liver cells.
- Central Stellate Scar: A star-shaped scar at the center of the lesion.
- Solitary Lesion: Typically, only one FNH growth is present.
- Prevalence in Females: It is more commonly found in women.
While FNH is not considered a disease, it's essential to differentiate it from other liver conditions, particularly those that are cancerous. Diagnostic imaging techniques, such as MRI or CT scans, are used to identify the characteristic features of FNH and rule out other potential causes.
Why FNH is Considered Benign
FNH doesn't typically progress to cancer or cause liver failure. In most cases, it doesn't require treatment, and individuals with FNH can live normal, healthy lives. Regular monitoring might be recommended to track the lesion's size and stability over time.
