FERNANDEZ LORENTE, Loreto et al. IgG4-related disease: description of a case with pulmonary lesions, mediastinal lymphadenopathies and rapidly progressive renal failure. []. , 35, 2, pp.218-223. ISSN 1989-2284.

A seventy-three year olded man was admitted because of acute kidney failure in the context of pulmonary infiltrates and mediastinic lympadenopathy under study. Urine test showed tubular range proteinuria with no microhematuria. Immunological testing showed an elevated IgG concentration and hypocomplementemia (classical pathway activation). Renal biopsy and clinical-pathologic correlation were crucial in this case, showing once again their important role in the final diagnosis of acute kidney injury.
