FNH is most commonly observed in which age/gender group?

• A. Women under 40
• B. Men under 40
• C. Children under 10
• D. Women over 60

Answer: (A)

FNH, or focal nodular hyperplasia, is a benign liver lesion seen most often in women of reproductive age. The link to this group comes from hormonal and vascular factors—estrogen exposure from oral contraceptives or hormonal changes during childbearing years can influence its development or how it appears on imaging. Because of that, the demographic most commonly affected is women under 40. While it can occur in other groups, they are much less common, such as men under 40, children under 10, or women over 60.
