Lobar consolidation: documented pneumonia
- Appearance
- Focal opacity
- Side
- Right lung
- Source context
- Lobar pneumonia
- Limitation
- Pathogen not identifiable
Morphological description
Describe the focal right-sided opacity, margins and presumed location. The source caption identifies right middle lobe involvement.
Causes and diagnostic direction
Fever, cough and a new radiographic abnormality support pneumonia. Appearance alone cannot distinguish bacterial from viral infection.
Differential diagnoses
Atelectasis, pulmonary infarction or a tumour may produce an opacity; reassess when the clinical course is unusual.
Pitfalls and limitations
Do not infer the pathogen from the radiograph. Persistent opacity requires individualised clinical and imaging reassessment.
Take-home message
Describe consolidation, relate it to symptoms and assess severity. Arrange follow-up according to symptoms and risk factors.
