Cleft like space in atheromatous plaque contains
**Core Concept**
Atheromatous plaques are complex lesions composed of lipid-laden macrophages, smooth muscle cells, and extracellular matrix. The characteristic feature of an atheromatous plaque is the presence of a lipid core, which is often surrounded by a fibrous cap. The lipid core can be divided into different regions, one of which is a cleft-like space.
**Why the Correct Answer is Right**
The cleft-like space in an atheromatous plaque is actually a region of necrotic core, where the lipid-laden macrophages have undergone necrosis due to the accumulation of lipids. This region is often referred to as the "necrotic core" or "lipid core". The necrotic core can be further divided into different regions, including the cleft-like space, which is a characteristic feature of an atheromatous plaque. The presence of the necrotic core is a hallmark of an advanced atheromatous plaque.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the cleft-like space in an atheromatous plaque.
**Option B:** This option is incorrect because it does not accurately describe the cleft-like space in an atheromatous plaque.
**Option D:** This option is incorrect because it does not accurately describe the cleft-like space in an atheromatous plaque.
**Clinical Pearl / High-Yield Fact**
It's essential to recognize the different regions of an atheromatous plaque, including the cleft-like space, to accurately diagnose and manage atherosclerotic cardiovascular disease.
**Correct Answer:** B. Lipid core.
