Cystic bronchiectasis


This case demonstrates the hallmarks of cystic bronchiectasis with bronchial wall thickening and dilated "cysts" visible on the chest x-ray, these correspond to fluid filled cystic bronchiectasis on CT.

The three subtypes of bronchiectasis, based on morphology are: 

  • cylindrical bronchiectasis
  • varicose bronchiectasis
    • uncommon, beaded appearances where dilated bronchi have interspersed sites of relative narrowing
  • cystic bronchiectasis
    • severe form with cyst-like bronchi that extend to the pleural surface
    • air-fluid levels are commonly present
