Ans:A. Pneumonia.
Image shows:Frontal CXR showing ill-defined air space opacification in the right lower lobe (arrows) due to consolidation from pneumonia.
Pneumonia
- The inflammatory exudate within air-spaces and interstitium of the affected lung causes the opacification and air-filled bronchioles outlined by adjacent fluid-filled alveoli in affected lung produce the air bronchogram.
