2. Figure
(a) US scan demonstrates a 5-cm right lobe lesion that is isoechoic to the surrounding parenchyma and abuts all three hepatic veins (arrows). (b) T2-weighted MR image demonstrates a lesion in the right lobe of the liver with a central scar (arrow). (c) Celiac arteriogram demonstrates a hypervascular lesion (arrows) supplied by branches of the right (arrowheads) and left hepatic artery. (d) Selective arteriogram of a small branch of the right hepatic artery with a microcatheter demonstrates extensive vascularity of the lesion (arrow). (e) Common hepatic arteriogram obtained after embolization demonstrates absent arterial blood flow to the target lesion. (f) CT scan obtained 1 month after embolization demonstrates the previous hypervascular lesion to now be almost entirely hypovascular (arrows). (g) CT scan obtained at 3-year follow-up shows minimal residual lesion (arrow) at the site of previous embolization.
