Fig. 1A. 66-year-old man with cholangiocellular carcinoma associated with
peritumoral sparing of fatty liver. Unenhanced CT scan shows irregularly
shaped hyperattenuating rim (arrow) in mildly fatty liver (A).
Size of surgically resected tumor corresponded to the central hypoattenuating
mass.
Fig. 1B. 66-year-old man with cholangiocellular carcinoma associated with
peritumoral sparing of fatty liver. CT scan during arterial portography
(B) and CT scan during hepatic arteriography (C) show perfusion
defect (B) and enhanced area (C) corresponding to central mass
and hyperattenuating rim in size and shape.
Fig. 1C. 66-year-old man with cholangiocellular carcinoma associated with
peritumoral sparing of fatty liver. CT scan during arterial portography
(B) and CT scan during hepatic arteriography (C) show perfusion
defect (B) and enhanced area (C) corresponding to central mass
and hyperattenuating rim in size and shape.
