Cystic bronchiectasis is one of the less common morphological forms of bronchiectasis. It may be present on its own or may occur in combination with other forms of bronchiectasis.
For a general discussion, please refer to the article on bronchiectasis.
It is characterized by saccular dilatation of bronchi that extends to the pleural surfaces. When aggregated these may give a "bunch of grapes" like appearance.
