Right lower lobe Pneumonia
➡️ Pneumonia refers to infection within the lung and results in infective fluid and pus filling the alveolar spaces. This initially results in patchy airspace opacification and then more confluent consolidation.
▪️Presentation:
- productive cough
- shortness of breath
- chest pain
▪️Chest radiograph:
➡️ Airspace opacification
- filling of the alveoli with infectious material and pus
- initially patchy
- becomes confluent as infection develops
➡️ Air bronchograms
- air-filled bronchi running through pus-filled alveoli
➡️ Complications
- pleural collection
- cavitation
▪️Treatment:
- In most cases, antibiotic therapy is all that is required
- This may be oral or intravenous, depending on the severity
