RATIONALE: Bronchial involvement alone is a rare initial manifestation of granulomatosis with polyangiitis (GPA). Herein, we report a case of refractory GPA with obstructive pneumonia caused by bronchial involvement. PATIENT CONCERNS: A 65-year-old man complained of a 2-week cough and fever. DIAGNOSES: Considering the presence of opacities and multiple consolidations in both lungs due to obstruction or stenosis on the bronchus, which did not respond to antibiotics, and proteinase-3-antineutrophil cytoplasmic autoantibody positivity, he was diagnosed with GPA. Positron emission tomography- computed tomography scan revealed no abnormal findings in the upper respiratory tract. INTERVENTIONS: He was treated with prednisolone (PSL, 50 mg/d) and intravenous cyclophosphamide. OUTCOMES: His general and respiratory symptoms improved. However, 8 weeks after PSL treatment at 20 mg/d, he developed a relapse of vasculitis along with sinusitis and hypertrophic pachymeningitis. Hence, PSL treatment was resumed to 50 mg/d, and weekly administration of rituximab was initiated. Consequently, the symptoms gradually mitigated. LESSONS: GPA with bronchial involvement is often intractable and requires careful follow-up, which should include upper respiratory tract and hypertrophic pachymeningitis assessment.
