PG - 3586-3590 LID - 10.3892/etm.2017.4440 [doi] AB - Pneumothorax and pleural effusion is a rare and serious complication of granulomatosis with polyangiitis (GPA). The present study reported a case with a history of sinusitis for 20 years, dry cough for three years and exacerbated purulent nasal discharge and recurrent skin ulcers for two years. The patient experienced sudden difficulty in breathing two months prior to presentation. Lung computed tomography (CT) showed multiple bilateral lung nodules and cavitary nodules as well as right hydropneumothorax. Paranasal sinus CT showed soft tissue infiltration. The cytoplasmic pattern of anti-neutrophil cytoplasmic antibody (c-ANCA) was positive and anti-proteinase 3 (PR3) antibodies, erythrocyte sedimentation rate and C-reactive protein were elevated. After pleural drainage and methylprednisolone pulse treatment, followed by cyclophosphamide and cyclosporine, the patient's symptoms were ameliorated, lungs were re-expanded, and c-ANCA, PR3 and inflammatory markers returned to normal levels.
