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
  • ​commonest form, bronchi have a uniform caliber, do not taper and have parallel walls (tram track sign and signet ring sign)
• 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
