Overview

There are three pathological types of bronchiectasis - Fusiform, Varicose, and Saccular.

Classification

There are three types of bronchiectasis, varying by level of severity.

• Fusiform (cylindrical) bronchiectasis also known as follicular bronchiectasis (the most common type)

• These are mildly inflamed bronchi that fail to taper distally.

• Varicose bronchiectasis

• The bronchial walls appear beaded because areas of dilation are mixed with areas of constriction.

• Saccular (cystic) bronchiectasis

• These arecharacterized by severe, irreversible ballooning of the bronchi peripherally, with or without air-fluid levels.
