Overview
Bronchiectasis may be classified according to its severity into 3 sub types: tubular/fusiform, varicose, and saccular. Bronchiectasis may also be classified according to its location into 2 sub types: localized and generalized.
Classification
Based on Severity
Based on severity, bronchiectasis may be classified as follows:
| Type | Features |
| Tubular or fusiform (cylindrical) bronchiectasis (follicular bronchiectasis) | Most common type. It is characterized by development of mildly inflamed bronchi that fail to taper distally[1][2] |
| Varicose bronchiectasis | The bronchial walls appear beaded because areas of dilation are mixed with areas of constriction |
| Saccular (cystic) bronchiectasis | These are characterized by severe, irreversible ballooning of the bronchi peripherally, with or without air-fluid levels |
Based on Location
Based on localization, bronchiectasis may be classified as follows:
| Location | Features |
|---|---|
| Localized | Confined to one lobe only |
| Generalized | Involves more than one lobe |
