Although Wegener's granulomatosis is known for almost 65 years, the disease is still a dilemma for physicians. This is probably due to its different clinical presentations or to the lack of diagnostic methods. The laboratorial diagnosis is supported on the presence of antineutrophil cytoplasmic antibodies (ANCA-c) and on histological analysis of tissues from affected organs. This paper describes a case report of a patient whose clinical history presented all protean aspects of the disease, including cardiac involvement such as myocarditis, pericarditis and, surprisingly, intracardiac mass.
