[Case report of limited form of Wegener's granulomatosis detected by a health examination with no subjective symptoms].

A 60-year-old woman with no subjective symptoms was admitted to our hospital because of chest radiograph abnormality detected by a health examination. A computed tomographic scan of the thorax showed multiple nodules in both lungs without cavitation. Other organ lesions were not detected. Specimens from transbronchial lung biopsy revealed non-specific granuloma with necrosis. Antituberculous therapy was not effective, and serum PR 3-ANCA revealed to be positive. So we performed an excisional biopsy of the lung by video-assisted thoracoscopic surgery. The specimens showed necrotizing vasculitides, and granulomata which consisted of mainly lymphocytes, epithelioid cells and Langhans' giant cells. We here report a rare case of a patient with a limited form of Wegener's granulomatosis suffering from no subjective symptoms detected by a health examination.
