In relapsing polychondritis, bronchiectasis appears to be secondary to primary bronchial damage with resultant recurrent infection. [59]

With inflammatory bowel disease, bronchiectasis has been seen in both ulcerative colitis and Crohn disease. The etiology remains unclear. Pulmonary symptoms may occur prior to the onset of bowel disease. [60]

Sarcoidosis may cause bronchiectasis by a variety of mechanisms, including parenchymal scarring, endobronchial granulomatous inflammation, or extrinsic compression of bronchi. [61]
