Wegener's granulomatosis (WG) is a systemic, granulomatous vasculitis that typically affects the upper airways, lungs, and, in most cases, the kidneys. Lung involvement occurs in 85% of patients. ⋯ These atypical pulmonary findings should raise suspicion of diseases other than WG and lead to biopsy with cultures, even when the diagnosis of WG appears to be certain. These guidelines proved to be reliable in a patient with WG in whom a hilar mass was associated with tuberculosis.
