Renal artery aneurysm. Polyaneurysmal lesion of kidney.

A case of innumerable renal artery aneurysms of probable congenital origin is reported. No other lesion could be found in any other abdominal organ studied. We think it unique as no similar case could be found in the medical literature. Except for right flank malaise, the patient was otherwise asymptomatic. The radiologic diagnostic methods are discussed, stressing the differential diagnosis of calcifications in the area of the kidney. The management of renal aneurysms is discussed in regard to the nephrectomy.
