Case 199: Hepatocellular Carcinoma (HCC)
77 year old man with incidental hepatic mass on CT angiography performed for evaluation of abdominal aortic aneurysm.
CT: Fatty variant
CT demonstrates cirrhosis and a large HCC with intratumoral fat (arrow on unenhanced image) in the right lobe that is predominantly hypovascular.
On the arterial phase series there is a hyperenhancing nodule along the lateral aspect of the HCC (arrowhead) with washout on the equilibrium phase (arrowhead).
The small central scar is better seen on MRI.
