In the evaluation of suspected HCC in a patient with cirrhosis, when is liver biopsy typically necessary?

When imaging shows characteristic features that meet LI-RADS criteria for HCC in a cirrhotic liver, a biopsy is not required to make the diagnosis. In cirrhosis, arterial phase hyperenhancement with washout in the portal or delayed phase is highly suggestive of HCC, and lesions categorized as LR-5 (definite HCC) allow noninvasive diagnosis based on imaging alone. Biopsy is reserved for situations where imaging is inconclusive or the liver is noncirrhotic, where imaging criteria are less definitive and histology may be needed to distinguish HCC from benign nodules or other malignancies. AFP elevation by itself is not diagnostic and does not mandate biopsy.
