Which of the following features most favours melioidosis rather than tuberculosis?
- Lobar consolidation
- Upper lobe predominance of nodular change
- Rapid progression of clinical features
- Lack of pleural involvement
There is significant overlap between the features of melioidosis, pneumonia and TB. However, in melioidosis, simultaneous involvement of other organs is common. Pleural involvement such as effusion, empyema, mediastinal or hilar adenopathy are rare, making them useful differentiating features from TB.
