Preferred Label : bronchiolectasis;
Definition : Pathology.—Bronchiolectasis is defined as dilatation of bronchioles. It is caused
by inflammatory airways disease (potentially reversible) or, more frequently, fibrosis.
CT scans.—When dilated bronchioles are filled with exudate and are thick walled, they
are visible as a tree-in-bud pattern or as centrilobular nodules (31,32). In traction
bronchiolectasis, the dilated bronchioles are seen as small, cystic, tubular airspaces,
associated with CT findings of fibrosis (Fig 12). (See also traction bronchiectasis
and traction bronchiolectasis, tree-in-bud pattern.) [Fleischner Society];
