Fig. 1B. 72-year-old man with hepatocellular carcinoma in hepatic
segment VI. Lesion (arrow) is seen as hyperattenuation on CT hepatic
arteriogram. At surgery, histopathologic findings revealed hepatocellular
carcinoma (not shown).

Fig. 2A. 45-year-old man with pseudolesion in hepatic segment II and
hepatocellular carcinoma in hepatic segment VIII. CT during arterial portogram
shows hypoattenuating wedge-shaped subcapsular lesion (black arrow)
in hepatic segment II suspected to be hepatocellular carcinoma. Another large
nodular hypoattenuating lesion (white arrows) is seen in hepatic
segment VIII.

Fig. 2B. 45-year-old man with pseudolesion in hepatic segment II and
hepatocellular carcinoma in hepatic segment VIII. Lesion (black solid
arrow) in hepatic segment II is seen as hyperattenuation on CT hepatic
arteriogram. Lesion (white solid arrows) in hepatic segment VIII is
seen as heterogeneous hyperattenuation. Peripheral portal vein branches
(open arrow) are well opacified.

Fig. 2C. 45-year-old man with pseudolesion in hepatic segment II and
hepatocellular carcinoma in hepatic segment VIII. Lesion in hepatic segment II
is not seen on follow-up CT scan obtained 20 months after A and
B. Large nodular mass (not shown) in hepatic segment VIII was
surgically removed and confirmed to be hepatocellular carcinoma.

Fig. 3A. 40-year-old man with pseudolesion and hepatocellular
carcinoma in hepatic segment V. CT during arterial portogram shows two
hypoattenuating lesions adjacent to gallbladder. Anterior lesion (solid
arrow) has nodular appearance, and posterior lesion (open
arrows) is wedge-shaped.

Fig. 3B. 40-year-old man with pseudolesion and hepatocellular
carcinoma in hepatic segment V. CT hepatic arteriogram shows hyperattenuation
in anterior lesion (arrow) and isoattenuation in posterior lesion. At
surgery, anterior lesion was confirmed to be hepatocellular carcinoma and
posterior lesion to be pseudolesion.

Fig. 4A. 40-year-old man with pseudolesion in hepatic segment V and
clinically proven hepatocellular carcinoma in segment III (not shown). CT
during arterial portogram shows nodular hypoattenuating subcapsular lesion
(solid arrows) in hepatic segment V. Another tiny hypoattenuating
subcapsular lesion (open arrow) is noted in same hepatic segment.

Fig. 4B. 40-year-old man with pseudolesion in hepatic segment V and
clinically proven hepatocellular carcinoma in segment III (not shown). Lesion
in segment V is seen as slightly hyperattenuating area on CT hepatic
arteriogram (solid arrows) and was prospectively interpreted as
hepatocellular carcinoma. Tiny lesion in same hepatic segment is seen as
wedge-shaped hyperattenuation (open arrow).

Fig. 4C. 40-year-old man with pseudolesion in hepatic segment V and
clinically proven hepatocellular carcinoma in segment III (not shown). On
follow-up CT scan obtained during hepatic arterial phase 10 months after
A and B, neither of two lesions is seen.

Fig. 5B. 59-year-old man with hepatocellular carcinoma in hepatic
segment IV. CT hepatic arteriogram obtained at same level as A shows
subtle hyperattenuating lesion (solid arrows) initially interpreted
as pseudolesion, such as arterioportal shunt, at our institution. Lesion was
surgically removed and confirmed to be hepatocellular carcinoma. Another
suspicious-appearing wedge-shaped hyperattenuating area in hepatic segment IV
(open arrows) is possibly due to nontumorous hemodynamic change.
