Abstract
Diffuse fatty infiltration is a common imaging finding due to the abnormal accumulation of lipids within hepatocytes. Baseline US is typically the first imaging modality for the evaluation of hepatic steatosis, but causing a conspicuous increase in liver echogenicity and a marked ultrasound beam attenuation, it really hampers FLL detection and characterization. Moreover, geographic fatty changes of the liver can occur when the fat accumulation ability of hepatocytes or fat deposition becomes heterogeneous throughout the liver and are classified into four subtypes: (a) focal fatty change, (b) multifocal steatosis, (c) lobar or segmental steatosis, and (d) focal fatty sparing in fatty liver [1].
