title: Acute bilateral renal artery occlusion due to granulomatous and necrotizing vasculitis.
abstract: A case of anuric acute renal failure due to bilateral renal artery obstruction in a 42 year-old man is presented. The obstruction was caused by bilateral thrombosis secondary to arteritis. Autopsy showed granulomatous and necrotizing vasculitis in both main renal arteries. Scarring and also necrotizing vasculitis were found from interlobular to arcuate renal arteries. The present case indicates that vasculitis should be considered when there is renal artery obstruction in young patients.
