Anterioposterior digital subtraction angiogram of the celiac artery: (a) early arterial phase shows arterial feeders which supply the hypervascular tumor. (b) Mid-arterial phase, revealing marked coarse neovascularity and significant arterio-venous shunting, as demonstrated by early visualization of the left and right portal veins (arrows), typical for hepatocellular carcinoma. (c) Late arterial phase, tumor blush and delayed contrast washout with persistent opacification of the portal system (arrows)

However, subsequent portal venous enhancement was noted, indicating hepatic arterial-portal venous shunting [Figure 1].
Computed tomography angiogram, axial and coronal images (a and b) indicating the site of the hepatocellular carcinoma in segments 7/8 (arrows). Corresponding axial and coronal SPECT/ CT images (c and d). Note only minimal accumulation of MAA in segment 7/8 tumor, while more intense tracer uptake is noted in the surrounding normal hepatic parenchyma
