Microscopic polyangiitis associated with sinobronchial syndrome.
A woman with a long history of chronic bronchitis and chronic sinusitis, i.e., sinobronchial syndrome, was admitted with a fever. Radiologically, there were areas of longstanding consolidation in both lungs, with areas of active inflammation demonstrated by gallium-67 scintigraphy. Antineutrophil cytoplasmic antibody specific for myeloperoxidase was highly positive. Pulmonary hemorrhage and hematuria occurred 2 weeks after admission and responded to steroid therapy. However, the patient died of pneumonia. An autopsy revealed systemic necrotizing vasculitis affecting multiple organs, consistent with microscopic polyangiitis. The vasculitis might have been caused by the chronic inflammation in the lungs associated with sinobronchial syndrome.
