The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
"Nutmeg liver" is a classic gross pathological description of the liver's cut surface.
It resembles the grated kernel of a nutmeg, displaying alternating dark red and light yellow-tan areas.
This characteristic pattern is caused by chronic hemodynamic disturbances that alter blood flow and oxygenation within the hepatic lobules.
Step 2: Detailed Explanation:
Let us analyze the pathophysiology of the hepatic lobule in chronic heart failure or central venous obstruction:
1. Chronic Venous Congestion (CVC):
CVC of the liver is typically caused by right-sided heart failure or obstruction of the vena cava.
This leads to increased pressure in the hepatic veins, which is transmitted back to the central veins of the hepatic lobules.
As a result, the central veins and surrounding sinusoids become distended with blood.
Because the centrilobular hepatocytes (Zone 3 of the Rappaport acinus) are furthest from the oxygen-rich hepatic arterioles, they suffer from severe hypoxia.
This hypoxia leads to centrilobular degeneration, necrosis, and loss of hepatocytes, which appears grossly as dark red, congested areas.
In contrast, the periportal hepatocytes (Zone 1) receive more oxygen-rich blood and survive, but they often undergo fatty degeneration (lipid accumulation) due to milder hypoxia.
These lipid-laden periportal areas appear pale yellow-tan.
The alternating pattern of dark red (congested, necrotic centrilobular zones) and pale yellow (fatty periportal zones) gives the liver its classic "nutmeg" appearance.
Therefore, this option is correct.
2. Cirrhosis:
Cirrhosis is characterized by diffuse fibrosis and nodular regeneration, which distorts the liver architecture but does not produce the classic nutmeg pattern.
3. Infarction:
Hepatic infarction is rare due to the liver's dual blood supply. When it occurs, it leads to localized coagulative necrosis.
4. Amyloidosis:
This leads to a diffuse, pale, waxy, and enlarged liver.
Step 3: Final Answer:
The characteristic "nutmeg liver" pattern is caused by chronic venous congestion, typically secondary to right-sided heart failure.
Therefore, the correct answer is option (D).
