Focal nodular hyperplasia

Focal nodular hyperplasia is a benign tumour of the liver, which is the second most prevalent tumour of the liver. It is usually asymptomatic, rarely grows or bleeds, and has no malignant potential. This tumour was once often resected because it was difficult to distinguish from hepatic adenoma, but with modern multiphase imaging is usually now diagnosed by strict imaging criteria and not resected.
