**Liver finding of child with Reye's syndrome**

**Core Concept**
Reye's syndrome is a rare but serious condition that causes swelling in the liver and brain. It is often associated with the use of aspirin in children during viral infections such as influenza or chickenpox. The liver finding in Reye's syndrome is characterized by microvesicular steatosis, which is a specific type of fatty liver disease.

**Why the Correct Answer is Right**
Microvesicular steatosis in Reye's syndrome is caused by the accumulation of small fat droplets within the hepatocytes. This is due to the inhibition of mitochondrial beta-oxidation of fatty acids, leading to the accumulation of triglycerides within the liver cells. The use of aspirin in children with viral infections disrupts the normal functioning of the mitochondria, resulting in the characteristic liver findings of Reye's syndrome.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the characteristic liver finding of Reye's syndrome. While liver dysfunction is a key feature, it is not specific enough to be the correct answer.
**Option B:** This option is incorrect because it does not accurately describe the type of liver damage seen in Reye's syndrome. Macrovesicular steatosis is a different type of fatty liver disease.
**Option C:** This option is incorrect because it does not mention the key feature of microvesicular steatosis in Reye's syndrome.

**Clinical Pearl / High-Yield Fact**
Reye's syndrome is a rare but serious condition that highlights the importance of avoiding aspirin use in children during viral infections. Remember the mnemonic "Aspirin in Children During Viral Infections" to remember the key risk factor for Reye's syndrome.

**Correct Answer: C. Microvesicular steatosis**
