[Bronchiolitis associated with ulcerative colitis]

Inflammatory bowel disease (IBD) only occasionally affects the lung. Noteworthy among the various pulmonary entities related to IBD are chronic bronchitis and bronchiectasis, though reports of bronchiolitis, obliterants bronchiolitis with organizing pneumonia and other interstitial diseases have also been published. Given the rarity of such pneumopathy, we report a case of bronchiolitis in a patient with a prior diagnosis of ulcerative colitis. We discuss the radiological findings and the results of lung function testing, emphasizin the utility of corticosteroid treatment, which usually leads to a good outcome in pneumopathy secondary to IBD.
