This report aims to show an unusual case of granulomatosis with polyangeitis (GPA), previously known as Wegener’s granulomatosis. It is a multisystemic disease characterized by necrotizing granulomatous inflammation and vasculitis involving mainly the upper and lower respiratory tract, although not infrequently, there is neurological impairment.
