Fig. 1A Axial CT angiography arterial phase images in 46-year-old
woman with hereditary hemorrhagic telangiectasia liver disease. CT angiogram
shows diffuse parenchymal heterogeneity and numerous telangiectases. All
patients in this study showed this heterogenous parenchymal enhancement
pattern.

Fig. 1B Axial CT angiography arterial phase images in 46-year-old
woman with hereditary hemorrhagic telangiectasia liver disease. Dilation and
early filling of main portal vein (arrow) during arterial phase are
consistent with arterioportal shunt.

Fig. 2 Axial CT angiography arterial phase image in 57-year-old
woman with symptomatic hereditary hemorrhagic telangiectasia liver disease
shows markedly dilated common hepatic artery that measures 18 mm in diameter
(arrow). Dilated common hepatic artery (> 4.5 mm) was seen in all
of our patients.

Fig. 3A Axial CT angiography arterial phase images in 64-year-old
woman with high-output cardiac failure subtype of hereditary hemorrhagic
telangiectasia liver disease. Marked dilation of common hepatic artery
(arrow) and extensive parenchymal heterogeneity and vascularity are
seen.

Fig. 3B Axial CT angiography arterial phase images in 64-year-old
woman with high-output cardiac failure subtype of hereditary hemorrhagic
telangiectasia liver disease. Early filling of right hepatic vein
(arrow) is consistent with arteriovenous shunt.

Fig. 4 Axial CT angiography image in 48-year-old woman with
symptomatic hereditary hemorrhagic telangiectasia liver disease. Early filling
of right, middle, and left hepatic veins (arrows) during arterial
phase of study is consistent with arteriovenous shunt.

Fig. 5A Axial CT angiography images of 62-year-old man with
symptomatic hereditary hemorrhagic telangiectasia liver disease. Opacification
of main portal vein (arrow) is seen during arterial phase, which is
consistent with arterioportal shunt. Splenomegaly is also present.

Fig. 5B Axial CT angiography images of 62-year-old man with
symptomatic hereditary hemorrhagic telangiectasia liver disease. Contour
nodularity and atrophy of right hepatic lobe are consistent with cirrhosislike
changes.

Fig. 6 Axial portovenous phase CT angiography image in 48-year-old
woman with biliary subtype of hereditary hemorrhagic telangiectasia liver
disease. Dilation of peripheral biliary branch in right hepatic lobe
(large arrow) is seen. Smaller areas of biliary dilation are also
present (small arrows).

Fig. 7A Multiple axial CT angiography images in 70-year-old woman
with hereditary hemorrhagic telangiectasia and liver disease show progression
of biliary disease. Baseline study shows characteristic heterogeneous hepatic
parenchyma and small biliary cyst in right hepatic lobe (arrow).

(arrow) has developed.

infected despite biliary drainage and antimicrobial therapy.

Fig. 7D Multiple axial CT angiography images in 70-year-old woman
with hereditary hemorrhagic telangiectasia and liver disease show progression
of biliary disease. Four days after C, biliary collection has markedly
increased. Patient died shortly after last study.
