Focal fatty infiltration of the liver in a healthy child

Fatty infiltration of the liver may occur in healthy children. The ultrasonographic, CT, and MRI findings are identical to those already described in the adult population. Diffuse or focal fatty infiltration of the liver is seen in adults with ethanol abuse, diabetes, obesity, high-dose steroids, and hyperlipidemia and has also been described in otherwise healthy adults [1]. The radiographic signs of diffuse fatty liver are well known [2], but focal fatty infiltration of the liver (FFIL) has been confused with abnormalities such as hepatic metastases in the adult population [3]. In the pediatric population, FFIL has not been previously described in normal children.
