A 4 year old girl presents with severe vomiting after viral fever of 6 days. She develops cerebral edema later on. What would be the liver biopsy finding?
## **Core Concept**
The question describes a clinical scenario suggestive of Reye's syndrome, a rare but serious condition that causes swelling in the liver and brain. Reye's syndrome typically occurs in children and teenagers recovering from a viral infection, often after the use of aspirin. The hallmark of Reye's syndrome is the development of severe vomiting and cerebral edema.
## **Why the Correct Answer is Right**
Reye's syndrome is characterized by **mitochondrial dysfunction**, leading to a shift from aerobic to anaerobic metabolism, resulting in lactic acidosis and microvesicular steatosis in the liver. The liver biopsy in Reye's syndrome shows **microvesicular fatty change**, where the hepatocytes contain numerous small fat droplets, giving a characteristic appearance.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option does not describe the characteristic microvesicular steatosis seen in Reye's syndrome.
- **Option B:** Similarly, this option does not match the expected liver biopsy findings in Reye's syndrome.
- **Option D:** This option also does not represent the typical microvesicular fatty change associated with Reye's syndrome.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that Reye's syndrome is strongly associated with the use of **aspirin** during viral infections in children. Therefore, aspirin should be avoided in children with viral infections to prevent this potentially fatal condition. The classic triad of Reye's syndrome includes **vomiting, altered mental status (cerebral edema), and liver dysfunction**.
## **Correct Answer:** . Microvesicular steatosis.
