Q) Which of the following statements about focal nodular hyperplasia (FNH) of the liver is true?
a) A central scar is present in all cases b) Fine-needle aspiration cytology (FNAC) is usually diagnostic in doubtful cases c) Resection is recommended due to risk of malignant transformation d) Asymptomatic patients with typical radiologic features usually do not require treatment
d) Asymptomatic patients with typical radiologic features usually do not require treatment
Focal Nodular Hyperplasia (FNH) is a benign liver lesion, often found incidentally.
a) Central scar is present in all cases – Incorrect. While a central stellate scar is characteristic of FNH, it is not present in all cases (seen in ~50-70% on imaging).
b) FNAC is usually diagnostic – Incorrect. FNAC often provides inconclusive results in FNH. Histological diagnosis requires tissue architecture, which FNAC can't reliably provide.
c) Resection is recommended due to risk of malignant transformation – Incorrect. FNH has no malignant potential and rarely causes complications. Surgery is not routinely recommended unless symptomatic or diagnosis is uncertain.
d) Asymptomatic patients with typical radiologic features usually do not require treatment – Correct. FNH with typical imaging features (especially on MRI with hepatobiliary contrast agents) does not require biopsy or surgical intervention.
