Diagnosis of Wegener's granulomatosis at the early stage is difficult because of the nonspecific symptoms which mimic other disorders. The aim of this paper is to describe clinical and radiological features of Wegener's granulomatosis (WG) in a Serbian population at initial presentation. A retrospective review of 37 patient's case records was carried out. All those patients were diagnosed with WG and they attended the Institute for lung diseases in Belgrade over the period of 15 years. There were 20 males and 17 females, ranging in age from 18 to 73 years (mean age 46.2 years). The mean period from the onset of the first symptoms to diagnosis of WG was 4.59 +/- 6.15 months. The criteria of American College of Rheumatology were fulfilled in all patients. Twenty-five of 37 patients had systemic, generalized form of WG and while 12 of them had a limited involvement of upper and lower respiratory system. The frequency of different system involvement was: upper respiratory tract 64.8%, lower respiratory tract 100%, kidneys 67.5%, musculoskeletal system 40.5%, skin 27.2%, eyes 8.1%, and nervous system two patients. ANCA (antineutrophil cytoplasmic antibodies) test was positive in 32 ((86.5%) patients, and negative in 5 (13.5%). All patients were ANA negative. Histological evidence of granulomatous vasculitis was obtained in 34 (91.9%), whereas in three patients the diagnosis was based on clinical manifestations and positive c-ANCA test. There are minor variations in our data when compared with those reported in literature.
