Bronchiolar dilatation
Bronchiolectasis is a descriptive term which is given to dilatation of bronchioles, which are of smaller caliber than bronchi. It can arise in a number of pathologies.
Pathology
Bronchiolectasis is most frequently seen secondary to fibrosis but can be seen with inflammatory airways disease. Bronchiolectasis can lead to centrilobular lung nodules or a tree in bud appearance if the bronchioles fill with exudate.
