The same regions correspond to spared areas in diffuse fat deposition (Fig. Some of them revealed multiple hepatic focal areas of persistent reduced attenuation in contrast-enhanced CT, or diffused hepatic lesions of increased signal intensity in arterial phase in contrast-enhanced MRI. Check for errors and try again. The classical patterns of focal fatty liver deposition and sparing are linked to vascular anatomical variants that involve capsular veins, peribiliary veins, the cystic vein (which drains perivesicular areas), and the right gastric vein (which drains the anterior portion of segment I and the posterior portion of segment IV).
