Bronchiolitis obliterans with Organizing Pneumonia Associated with Acute <i>Coxiella burnetii </i>Infection

We report the case of a 62-year-old man who developed bronchiolitis obliterans with organizing pneumonia (BOOP) associated with acute <i>Coxiella burnetii </i>infection. The diagnosis of BOOP was made by fiber-optic transbronchial biopsy. Treatment with corticosteroids resulted in rapid clinical improvement and complete resolution of airspace opacities. To the best of our knowledge, this is the first well-documented case of BOOP associated with <i>C. burnetii </i>infection. This case suggests that this infection might trigger the development of BOOP.
