Complication of post-infectious bronchiolitis obliterans (Swyer-James syndrome).

Swyer-James syndrome is a complication of post-infectious bronchiolitis obliterans that causes inflammation and fibrosis of the bronchial walls. There are two types: asymptomatic, with most cases diagnosed in adults during routine radiological examinations; and symptomatic, most commonly found in children. Here, we report the case of a 6-year-old child with recurrent dyspnea since the age of 3, who showed signs and symptoms of bronchiolitis obliterans and radiological signs of bronchial wall thickening and air trapping. The clinical and radiological findings led to the diagnosis of Swyer-James syndrome. Treatment of this syndrome is intended to reduce the pulmonary lesions and improve the patient's quality of life.
