What is focal fatty infiltration?

Focal fatty infiltration refers to the localized accumulation of fat within the liver tissue, often seen on imaging studies such as ultrasound or MRI. It can occur in a variety of conditions, including obesity, Diabetes, and certain liver diseases, and may sometimes be mistaken for liver lesions. While generally considered benign, it can be associated with underlying metabolic disorders and may require monitoring or further investigation if other liver abnormalities are present.
