[Renal cholesterol embolism. Apropos of 13 cases].
Between January 1981 and April 1988, histologically proven renal cholesterol embolism was diagnosed in 13 men over 60 years of age with a previous history of hypertension and atherosclerosis. Six patients developed acute renal failure, usually induced by a triggering factor such as angiographic procedure or anticoagulation, and associated with peripheral and visceral cholesterol embolism, eosinophilia and a high sedimentation rate. In this group of patients, whose protean clinical manifestations and laboratory data mimicked necrotizing angiitis despite the absence of antineutrophil cytoplasmic antibodies, skin lesion biopsy established the diagnosis and made renal biopsy unnecessary. Six patients had chronic renal failure and elevated sedimentation rate, and the last patient had isolated microhematuria. In these 7 patients, percutaneous renal biopsy was an adequate procedure for the diagnosis of cholesterol embolism. As medical management of cholesterol embolism is essentially preventive, these unusual presentations must be emphasized.
