Likely result of inappropriate immune response to physiologic gut flora in host with genetic susceptibility
Includes ulcerative colitis (UC) and Crohn disease (CD)
UC: Limited to colon
CD: Any segment of gastrointestinal tract
Extraintestinal manifestations of IBD are present in 16-40% of affected patients but are more common in CD
Pulmonary manifestations are rare but often overlooked
May be secondary to disease itself or may occur as complication of drugs used to treat disease (e.g., drug toxicity, opportunistic infection)
