Pyopneumothorax: a rare complication of Wegener's granulomatosis

We present a case of Wegener's granulomatosis, complicated by the development of pyopneumothorax due to the rupture of a cavity. This complication occurred despite treatment with corticosteroids and cyclophosphamide. Active vasculitis and impaired tissue repair are possible explanations for the occurrence of this complication and the fatal outcome in our patient.
