Non-alcoholic steatosis (non-alcoholic fatty liver disease [NAFLD]) is mainly observed in patients with metabolic syndrome; what is more, it is considered as the hepatic manifestation of this syndrome. Common patterns include diffuse fat accumulation, diffuse fat accumulation with focal sparing, and focal fat accumulation in an otherwise normal liver.
