Renal arteriovenous fistulas are uncom-mon lesions. Malignancies are one of the un-derlying cause of arteriovenous fistulas.

Herein we present the case of a 48-year-old man who was presented with heart failure and continuous murmur over the left costoverteb-ral angle. Contrast enhanced computerized to-mography showed enlarged left renal vein and arteriovenous fistula on the left kidney. Selecti-ve renal angiography confirmed the presence of extremely dilated left renal vein with high-flow arteriovenous fistula.

Abstract
Renal arteriovenous fistulas are uncom-mon lesions. Malignancies are one of the un-derlying cause of arteriovenous fistulas. The cli-nical manifestation of these lesions vary widely, from asymptomatic presentation to hypertensi-on. Herein we present the case of a 48-year-old man who was presented with heart failure and continuous murmur over the left costoverteb-ral angle. Contrast enhanced computerized to-mography showed enlarged left renal vein and arteriovenous fistula on the left kidney. Selecti-ve renal angiography confirmed the presence of extremely dilated left renal vein with high-flow arteriovenous fistula. We performed nephrec-tomy because of the large size and high-output of the fistula.The pathology revealed renal cell carcinoma. In the first month follow-up his symptoms were regressed.
Key Words: Heart failure; renal arteriove-nous fistula; renal cell carcinoma; nephrectomy.
