Focal fatty infiltration and focal fatty sparing can be related to normal variation or pathologic alteration in hepatic hemodynamics. The association between diminished portal supply and uneven fatty infiltration has been intensively investigated in cases with nonportal splanchnic venous supplies to the hepatic parenchyma. Likewise, focal fatty sparing can be induced by arterioportal shunt occurring in various conditions, including hepatocellular carcinoma and hepatic hemangioma. Although it is generally believed that a decrease in portal flow can induce focal fatty sparing, a decrease in portal flow may ironically induce focal fatty infiltration in some cases. Therefore, the underlying mechanism of uneven fatty liver is still not clear. Recognition of these focal processes prevents false-positive diagnosis and can help in the interpretation of unusual imaging findings of a hepatic disease complicated by accompanying uneven fatty infiltrations. This exhibit illustrates typical and unusual cases of uneven fatty infiltrations, with relevant pictorial analyses of their underlying hemodynamics.
1. To understand typical findings and distribution of uneven fatty infiltrations in the liver. 2. To understand how uneven fatty infiltrations can be explained by hepatic hemodynamic alterations. 3. To understand how unusual imaging findings of a hepatic disease can be easily explained with uneven fatty infiltration.
