[The cest radiograph in Wegener's granuloma (author's transl)]

Wegener's granuloma belongs to the so-called collagenoses. It is characterized by focal vasculitis, necrotising granulomatous processes in the upper air passages and lung, as well as focal glomerulitis with swelling of the capsule and the formation of granulomatous glomerular lesions. In order of frequency the lungs, paranasal sinuses, pharynx, kidneys, joints, skin, eyes, ears, the heart and nerve tissue may be involved. Recently, Wolf and Fischbach (1976) reported six cases of Wegener's granuloma in this Journal, with radiological and pathological changes in the lungs. Typical changes which may be found radiographically are illustrated in the present paper based on four histologically confirmed cases of this relatively rare condition.
