Wegener's granulomatosis: Pitfalls in the management of pulmonary disease.A case of Wegener's granulomatosis with a hilar mass

Wegener's granulomatosis (WG) is a systemic, granulomatous vasculitis that typically affects the upper airways, lungs, and, in most eases, the kidneys . Lung involvement occurs in 85% of patients. A classic feature of WG is mu ltiple pulmonary nodules, which frequently cavitate. Hilar adenopathy or me diastinal masses are rare. These atypical pulmonary findings should raise s uspicion of diseases other than WG and lead to biopsy with cultures, even w hen the diagnosis of WG appears to be certain. These guidelines proved to h e reliable in a patient with WG in whom a hilar mass was associated with tu berculosis.
