Kidney Biopsy Findings in a Patient With Fever, Bilateral Pulmonary Infiltrates, and Acute Renal Failure

摘要

An early diagnosis is necessary in patients . presenting with pulmonary disease and acute renal failure to initiate the proper therapy and avoid irreversible renal and/or pulmonary damage or death. The differential diagnosis in such cases includes several distinct clinicopatho-logical entities, such as Goodpasture syndrome, Wegener granulomatosis and other vasculitides, systemic lupus erythematosus, Henoch-Schon-lein purpura, sarcoidosis, and systemic infections. Correct diagnosis requires a combination of clinical, laboratory, and histopathologic findings. We present a case that illustrates how detailed histopathologic examination on renal biopsy can be essential in making a correct diagnosis in a patient with an elusive clinical picture
