Pulmonary diseases associated with inflammatory bowel diseases.

Among the extra-intestinal manifestations of inflammatory bowel diseases, those involving the lung are relatively rare. However, there is a wide array of such manifestations, spanning from drug-related pathologies to airway disease, fistulas, granulomatous diseases, autoimmune and thromboembolic disorders. Although infrequent, people dealing with inflammatory bowel diseases must be aware of these conditions, sometimes life-threatening, to avoid further impairment of the health status of the patients and to alleviate their symptoms by prompt recognition and treatment.
