Most common cause for macro nodular cirrhosis?

Most common cause for macro nodular cirrhosis?

• A. Chronic viral hepatitis
• B. Alcohol consumption
• C. Autoimmune hepatitis
• D. Nonalcoholic fatty liver disease

Answer: (A)

Macronodular cirrhosis forms when chronic liver injury drives repeated cycles of hepatocyte death and regeneration, with fibrous bands bridging these regenerating areas to create larger nodules. Chronic viral hepatitis (hepatitis B and C) is the most common cause of cirrhosis that develops this macronodular pattern, because the ongoing inflammation and necrosis promote larger regenerative nodules. Alcohol can cause cirrhosis and may produce nodularity as well, but viral hepatitis remains the more frequent etiologic association with macronodular morphology. In ultrasound, you’d expect a liver with an irregular, lobulated contour and coarse echotexture consistent with regenerative nodules and bridging fibrosis, often with signs of portal hypertension if advanced.
