What does focal fatty sparing of the liver mean?

We often found a high attenuation region around the gallbladder bed in the fatty liver patients on CT examination. There appears to be some relationship between the high density around the gallbladder area and the fatty liver.

What causes Focal fatty sparing and Focal fatty change?

Similar to its inverse pathological counterpart, focal fatty change, regions of focal fatty sparing are thought to have altered perfusion compared to the rest of the liver. The cause of this is incompletely understood. In the context of metastases, this may be due to compression/invasion of portal venules by tumor 3.
