Crohn's disease (CD) is a complex, multifactorial disease that is characterized by chronic inflammation of the gastrointestinal system (1). It may affect any part of the gastrointestinal tract from the mouth to the anus. Approximately 25-40% of patients with CD can have multiple extraintestinal manifestations, including erythema nodosum, pyoderma gangrenosum, ankylosing spondylitis, arthritis, hepatitis, sclerosing cholangitis, pancreatitis, nephrolithiasis, uveitis, and episcleritis (2). The first report of lung involvement in CD was published in 1976 (3). The bronchopulmonary manifestations of CD are very rare extraintestinal manifestations, and the literature reports that the prevalence of these manifestations is as low as 0.2% (4). However, this prevalence rate may be underestimated, as an increasing number of cases have reported that the pulmonary performance of adult CD patients may be higher than was previously thought. Reports of children with CD involving the lungs are even rarer; thus, lung lesions are often overlooked. This article reports of one pediatric CD patient presenting
