**Core Concept**
Liquefaction necrosis is a type of coagulative necrosis characterized by the breakdown of tissue structure and the release of cellular enzymes, leading to the formation of fluid-filled cavities. This process is often observed in brain tissue following ischemic injury or infection.

**Why the Correct Answer is Right**
Liquefaction foci of Miller are a hallmark feature of cerebral abscesses, which result from the invasion of the brain by bacteria or fungi. The infection triggers an inflammatory response, leading to the release of enzymes such as collagenase and hyaluronidase, which break down the surrounding tissue and create fluid-filled cavities. These cavities, or liquefaction foci, are characteristic of the abscess and can be visualized on histopathological examination.

**Why Each Wrong Option is Incorrect**
**Option A:** Not applicable, as liquefaction foci of Miller are specific to cerebral abscesses.
**Option B:** While infarction can cause liquefaction necrosis, it is not characterized by the formation of distinct liquefaction foci.
**Option C:** Tumor necrosis can be confused with liquefaction necrosis, but it typically has a more heterogeneous appearance and is not typically associated with the formation of distinct liquefaction foci.

**Clinical Pearl / High-Yield Fact**
When evaluating a patient with a suspected cerebral abscess, it is essential to consider the histopathological features, including the presence of liquefaction foci of Miller, to guide diagnosis and treatment.

**Correct Answer: C. Cerebral abscess.**
