Abstract

Several types of infection can cause organizing pneumonia when the inflammatory process remains active with the further organization of the intra-alveolar fibrinous exudates, despite the control of the infectious organism by antibiotics. We report a case of 37-year-old male with secondary organizing pneumonia associated with an endobronchial actinomycosis. The patient presented with a subacute cough, sputum and fever. Bronchial biopsy revealed sulfur granule to be consistent with the actinomycosis, and percutaneous needle biopsy revealed typical pattern of organizing pneumonia. The patient was treated with the appropriate antibiotics and corticosteroid. There was rapid improvement in the symptoms and radiological findings, and after six months of treatment, the corticosteroid dose was tapered off without a recurrence of the organizing pneumonia.
