Case report demonstrates early-stage diffuse panbronchiolitis resolution in a young patient, highlighting the importance of macrolide therapy before irreversible lung damage.
A 29-year-old man presented with sputum and cough, which were pointed out by his neighbors. A high-resolution chest computed tomography scan showed well-defined multiple centrilobular nodules and a tree-in-bud pattern. Chest auscultation revealed coarse crackles. He did not report any nasal sinus symptoms. We subsequently performed a video-assisted lung biopsy; the specimen confirmed diffuse panbronchiolitis. Subsequently, sinusitis was confirmed by an otolaryngologist. His symptoms gradually improved following treatment with erythromycin. We report a case of early-stage diffuse panbronchiolitis in a young patient, with multiple intralobular nodules, no bronchiectasis, and a good clinical course.
