Unclassified hepatic adenoma
Citation, DOI and article data
Unclassified hepatic adenomas refer to the 5-10% of hepatocellular adenomas subtype that lack known genetic abnormalities1,2. These adenomas cannot be further categorized genetically or histologically as inflammatory adenomas, HNF 1 alpha mutated adenomas or beta-catenin mutated adenomas.
The clinical features of these adenomas remain poorly understood. No specific MR imaging features have been proposed to identify unclassified hepatocellular adenomas1.
