    Abstract:
    Wegener's granulomatosis is a potentially life-threatening vasculitis with widely variable presentation. Only three pediatric cases with severe central nervous system involvement are reported in the literature. Early fatal outcome as described here is exceptional. This report describes a 13-year-old female with typical skin lesions, proteinuria, and renal failure initially misdiagnosed as a Schoenlein-Henoch purpura. A kidney biopsy revealed severe extracapillary proliferation in 70% of the analyzed glomeruli but no granuloma. In spite of methylprednisolone pulse therapy and oral high-dose prednisone, end-stage renal failure was reached 4 months later, necessitating peritoneal dialysis. Three months later she presented with pulmonary hemorrhage and positive antineutrophil cytoplasmic antibodies suggesting Wegener's granulomatosis. This episode was controlled by methylprednisolone pulses. Seven months later she presented generalized seizures and coma, suggesting central nervous system involvement confirmed by magnetic resonance imaging. Methylprednisolone pulses and intravenous immunoglobulins led to neurologic improvement. Oral methotrexate was then introduced for long-term disease control. Another severe relapse of central nervous system vasculitis did not respond to any applied therapies and led to death 16 months after initial symptoms. This case emphasizes the need for activity scores to identify patients at risk for progressive systemic vasculitis requiring early and long-term aggressive immunosuppressive therapy.
