Fig. 3D 44-year-old woman with hepatic steatosis. Peritumoral sparing
of fatty infiltration around high-flow hemangioma is seen with arterioportal
shunt. Unenhanced CT scan shows decrease of hepatic attenuation, suggestive of
hepatic steatosis, and also shows thin hyperdense peritumoral rim
(arrowheads), which corresponds to geographic peritumoral hypoechoic
area at sonography, suggesting peritumoral sparing of fatty infiltration.
