OBJECTIVE. Wegener's granulomatosis is an uncommon necrotizing vasculitis having variable presentations in the chest that are best depicted on high-resolution CT. Imaging findings may include nodules, which may cavitate; ground-glass opacity secondary to pulmonary hemorrhage; and airway stenoses and ulcerations. Active Wegener's granulomatosis can mimic pneumonia, septic emboli, and metastases.

CONCLUSION. This article will illustrate the high-resolution CT findings of Wegener's granulomatosis in the chest.

Keywords: high-resolution CT • vasculitis • Wegener's granulomatosis
