Liquefactive necrosis is seen in:
**Core Concept**
Liquefactive necrosis is a type of coagulative necrosis characterized by the digestion of dead tissue cells, resulting in the liquefaction of the affected area. This process is typically seen in tissues with a high fat and water content, such as the brain and liver.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of liquefactive necrosis, which involves the action of enzymes such as lysosomal cathepsins and lipases that break down cellular components. In the brain, the high lipid content makes it more susceptible to liquefactive necrosis, resulting in the formation of a soft, cheesy mass. This process is often seen in conditions such as cerebral infarction and brain tumors.
**Why Each Wrong Option is Incorrect**
* **Option A:** Cortical infarction is more likely to result in coagulative necrosis, not liquefactive necrosis.
* **Option B:** Liver abscesses may result in caseous necrosis, but not liquefactive necrosis.
* **Option C:** Myocardial infarction typically results in coagulative necrosis, not liquefactive necrosis.
**Clinical Pearl / High-Yield Fact**
Liquefactive necrosis is often associated with conditions that involve the breakdown of cellular membranes and the release of lysosomal enzymes, such as cerebral edema and hemorrhagic stroke.
**Correct Answer:** B. Liver.
