Here, We are going to discuss the differential diagnosis(DDx) and complications of lung abscess .
• Lung abscess
- Acute onset
- The expectoration increases on lying on healthy side
- Retension $ is common (i.e. attacks of cough with expectoration of large amount of sputum and evacuation of the cavity and then reaccumulation occurs )
• Bronchiectasis
- Gradual onset
- Long duration
- It is bilateral, basal so the expectoration increases with leaning forward .
• Infected cystic lung
• Empyema with bronchopleural fistula diagnosed by (Methylene blue test)
i.e. injection of methylene blue into pleural space -7 bluish colouration of the sputum.
• Pleurisy, pleural effusion and empyema.
• Bronchiectasis and fibrosis
• Amyloidosis e.g in kidney ---> Nephrotic $

Complications of lung abscess:
• Pneumonitis• Pleurisy, pleural effusion and empyema.
• Bronchiectasis and fibrosis
• Amyloidosis e.g in kidney ---> Nephrotic $
