Inclusion body containing glycogen is seen in ?
**Core Concept**
The question is testing knowledge of cellular inclusions, specifically those containing **glycogen**. Inclusion bodies are abnormal structures within cells that can be composed of various substances, including proteins, viruses, and metabolic byproducts like glycogen.
**Why the Correct Answer is Right**
Given the correct answer is related to a condition where glycogen accumulation is a hallmark, it likely involves a disorder of glycogen metabolism. **Pompe disease** is a glycogen storage disease characterized by the accumulation of glycogen in lysosomes due to an enzyme deficiency, leading to cellular dysfunction.
**Why Each Wrong Option is Incorrect**
**Option A:** This choice is incorrect because it does not directly relate to glycogen accumulation.
**Option B:** Similarly, this option does not specifically involve glycogen storage.
**Option C:** This choice is also incorrect as it is not primarily associated with glycogen inclusions.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **glycogen storage diseases** like Pompe disease result from enzyme deficiencies affecting glycogen metabolism, leading to accumulation in various tissues, including muscle.
**Correct Answer:** D. Pompe disease
