Discussion WG is a systemic disease characterized pathologically by the presence of
necrotizing granulomatous lesions of the upper and lower respiratory tracts and a
generalized vasculitis of small to medium-sized vessels, often associated with a
glomerulonephritis [4]. Kidney involvement is common, but extrarenal manifestations usually

segmental necrotizing glomerulonephritis, with or without crescents, and rarely …

Wegener's granulomatosis (WG) is a disease of unknown etiology characterized by

involvements are very common; however, its presentation as bilateral renal masses is
unusual. We report a case of a 59-year-old female patient who presented with multiple
