title: Wegener granulomatosis--an atypical case.
abstract: An unusual sequence of the clinical manifestations of microvascular disease is described in a 15 year-old girl. She initially presented with acute renal failure caused by a crescentic glomerulonephritis associated with positive tests for MPO-ANCA. Eighteen months later she had pulmonary hemorrhage and respiratory failure. An open lung biopsy showed granulomas that were diagnostic for Wegener granulomatosis. We discuss the diagnostic dilemmas faced in attempts to distinguish infective causes of pulmonary granulomas, such as tuberculosis or fungi, from granulomas associated with vasculitis, in a patient previously treated with immunosuppressive therapy.
