Which benign liver tumor is more common in women than men and has a central scar?

Focal nodular hyperplasia (FNH) is recognized as a benign liver tumor that tends to be more prevalent in women compared to men. One of the distinctive characteristics of FNH is the presence of a central scar, which can be observed during imaging studies such as ultrasound or MRI. This central scar is formed by fibrous tissue and is a key feature that helps differentiate FNH from other liver lesions.

In addition to the central scar, FNH is typically asymptomatic and does not progress to malignancy, making it important in clinical practice to correctly identify it during evaluations of liver lesions. This tumor commonly arises in young to middle-aged women and is often found incidentally during imaging performed for other reasons.

Understanding the demographics and characteristic imaging features of FNH is crucial for healthcare professionals when assessing and managing liver tumors, ensuring that benign conditions are not misidentified as malignant.
