The most common benign tumour of the liver, often found incidentally on imaging as a well-defined lesion that may show peripheral discontinuous enhancement with progressive centripetal filling, is:
- A Focal nodular hyperplasia
- B Hepatocellular adenoma
- C Cavernous haemangioma ✓
- D Hepatic hamartoma
Correct answer: C. Cavernous haemangioma
Explanation
Cavernous haemangioma is the commonest benign neoplasm of the liver, with a prevalence up to 20% in autopsy series. The characteristic imaging pattern is peripheral nodular discontinuous enhancement on arterial phase with centripetal progression on delayed phases. Focal nodular hyperplasia shows a central scar with homogeneous arterial enhancement, and hepatocellular adenoma is strongly linked to oral contraceptives and risks haemorrhage, so neither matches the described pattern.
