Reviewer’s report:  
 
Please emphasize that no patients with FNH had cirrhosis in  your comments. If a patient has 
known cirrhosis and is found to have a new focal liver lesion, it is unlikely a focal nodular 
hyperplasia. Even if it  has radiologic characteristics of possible FNH, a liver biopsy would  be 
mandatory.
