Which imaging pattern is most consistent with bronchopneumonia?

• A. Diffuse interstitial markings without focal consolidation.
• B. Consolidation limited to a single lobe.
• C. Diffuse alveolar edema pattern.
• D. Patchy, multifocal air-space opacities around bronchi.

Answer: (D)

Bronchopneumonia characteristically shows patchy, multifocal air-space opacities centered around the bronchi and bronchioles. This pattern reflects infection spreading along the airways with inflammation around the bronchial walls, producing scattered, irregular opacities that can involve several lobes and often appear bilateral. It contrasts with lobar pneumonia, which presents as a dense, consolidation limited to a single lobe. Interstitial or viral patterns tend to show diffuse interstitial markings rather than discrete air-space patches, and edema typically shows vascular congestion and a perihilar pattern rather than clustered opacities around bronchi. So the patchy, multifocal air-space opacities around bronchi best fit bronchopneumonia.
