What is a hallmark feature of fatty liver?

• A. Reversible fat accumulation in liver cells
• B. Irreversible scarring of liver tissue
• C. Inflammation and liver cell injury
• D. Cancerous growth

Answer: (A)

Fatty liver is defined by fat accumulating inside liver cells, specifically triglycerides stored in hepatocytes. This fat buildup is reversible, especially if alcohol is stopped and metabolic factors are managed, so early fatty liver can improve or disappear. That reversible fat accumulation is the hallmark that distinguishes simple fatty liver from more advanced liver damage. If the condition progresses, inflammation and liver cell injury can occur (alcoholic hepatitis), and chronic damage can lead to scarring (fibrosis or cirrhosis), but those are not the defining feature of fatty liver. Cancerous growth is not a characteristic of fatty liver.
