All are true about white infarcts except?
## Core Concept
White infarcts, also known as anemic infarcts, occur due to arterial occlusion in solid organs with a single blood supply, leading to coagulative necrosis. This type of infarct is typically seen in the heart, kidney, and spleen.
## Why the Correct Answer is Right
The correct answer, , implies that an option stating something not characteristic of white infarcts is chosen. White infarcts are indeed characterized by their occurrence in solid organs with end-arterial supply (like the heart and kidneys), and they appear pale due to the lack of blood flow and subsequent coagulative necrosis.
## Why Each Wrong Option is Incorrect
- **Option A:** Typically, white infarcts are associated with arterial occlusion. If an option suggests that white infarcts are usually caused by venous occlusion, it would be incorrect because venous occlusions more commonly lead to hemorrhagic infarcts, especially in organs like the lung or liver.
- **Option B:** If an option states that white infarcts occur in solid organs with a single blood supply, it would actually be a correct statement about white infarcts, making it an incorrect choice as an exception.
- **Option C:** Similarly, if an option mentions coagulative necrosis as a feature of white infarcts, it would be correct and thus not the exception.
- **Option D:** Without the specific details of each option, if is the correct answer, it implies that the statement in does not hold true for white infarcts.
## Clinical Pearl / High-Yield Fact
A key point to remember is that white infarcts are typically seen in the heart, kidneys, and spleen, and they are a result of arterial occlusion leading to coagulative necrosis. This is in contrast to hemorrhagic infarcts, which are often seen in lungs and liver and are associated with venous occlusion or dual blood supply.
## Correct Answer: D.
