Role of FNA and Core Biopsy of Primary and Metastatic Liver Disease
Figure 4
. History: 51 year-old-male with no cirrhosis, AFP 1.8, and no hepatitis. At surgery this was pathologically proven to represent liver adenoma. (a) Arterial phase CT demonstrating enhancing mass with lobulated margin (arrow). (b) Delay images demonstrating persisting enhancement (arrow) with focal hypodense area noted centrally. This was considered an equivocal mass on review. (c) Fine needle aspiration biopsy with three passes and three core biopsies demonstrated epithelial neoplasm and adenoma versus HCC. This was reviewed at an outside institution with the diagnosis of well-differentiated HCC. The smears are cellular and show hepatocytes with minimal atypia in sheets and small clusters. Prominent capillaries are noted within the sheets and endothelial cells are noted to be encircling clusters of hepatocytes. Post-surgery pathology revealed this to be adenoma.
