Fibrolamellar hepatocellular carcinoma: multiphasic CT features of the primary tumor on pre-therapy CT and pattern of distant metastases.

FLHCC typically manifests as a large, solitary mass demonstrating heterogeneous hypervascular enhancement in the arterial phase. Most tend to be isoattenuating in delayed phase. Central stellate scar with internal calcification is a useful imaging feature that can help in the diagnosis of FLHCC. Lungs are the most common site of distant metastases in FLHCC.
