Capability of multidetector CT to diagnose hepatocellular carcinoma-associated arterioportal shunt

Figure 1 Diffuse pattern of HCC complicated with severe and central APS. Earlier enhancement and stronger opacification of main portal trunk, left and right first-order branches, with thromboses in them; decreased enhancement degrees of HCC foci and spleen, and ascites were also displayed (A, B). DSA finding of the same patient (C).

Figure 2 Massive pattern of HCC associated with mild and peripheral APS. Transient wedge-shaped enhancement anterior to HCC foci at late hepatic arterial phase (A), becoming isoattenuation at portal vein phase (B); decreased enhancement degree of HCC focus was disclosed too. The APS was missed with DSA (not shown).

Figure 3 Massive pattern of HCC accompanied with severe, central and slight, peripheral APS. Earlier enhancement and stronger opacification of main portal trunk, left and right first-order branches, with thromboses in them and transient patchy enhancement at late hepatic arterial phase (A), becoming isoattenuation at portal vein phase (B); decreased enhancement degrees of HCC focus and spleen, cirrhotic liver and ascites were also shown. DSA finding of the same patient (C).
