Unclassified hepatic adenomas refer to the 5-10% of hepatocellular adenomas subtype that lack known genetic abnormalities 1,2. 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 adenomas 1.
