**Core Concept**
Cardiogenic pulmonary edema is a condition characterized by the accumulation of fluid in the lungs due to left heart failure, leading to impaired gas exchange and respiratory distress. In this context, radiological features help in diagnosing and assessing the severity of pulmonary edema.
**Why the Correct Answer is Right**
Cardiogenic pulmonary edema is typically associated with increased vascular permeability and fluid accumulation in the alveolar spaces. The characteristic radiological features include **ground-glass opacities**, **alveolar consolidation**, and **peribronchial cuffing**. These features result from the interstitial and alveolar edema, which can be visualized on chest radiographs.
**Why Each Wrong Option is Incorrect**
**Option A:** Kerley B lines, which are short, horizontal lines at the lung periphery, are indeed characteristic of cardiogenic pulmonary edema due to interstitial edema.
**Option B:** Alveolar consolidation is a hallmark of cardiogenic pulmonary edema, representing fluid-filled alveoli.
**Option C:** Peribronchial cuffing, resulting from interstitial edema, is also a characteristic feature of cardiogenic pulmonary edema.
**Clinical Pearl / High-Yield Fact**
In cardiogenic pulmonary edema, the presence of **perihilar opacities** and **alveolar edema** on chest radiographs can be indicative of increased pulmonary capillary wedge pressure, suggesting left heart failure.
