   Introduction
 
Renal arteriovenous fistulae (AVFs) and associated aneurysmal malformations, located either intra- or extrarenally [1], are rare and characterized by a single cavernous communication between the artery and the venous outflow [2]. Clinically they may present with flank bruit and pain, haematuria, uncontrolled hypertension [3] and high-output cardiac failure. Whereas compromise in renal and cardiac function in cases of large shunt volumes is caused by AVFs, rupture with severe bleeding is most feared as a complication of renal aneurysms.

We describe the diagnostic, therapeutic and follow-up radiological findings in an unusual case, highlighting a possible complication after embolization therapy in a patient with von Willebrand factor (vWF) syndrome.



   Case
 
At the end of 2003, a 57-year-old woman was referred for control of a renal artery aneurysm diagnosed incidentally in 1991 as she had felt palpitations in the left flank for 2 weeks. Concomitant morbidities were varicosis, . . . [Full Text of this Article]
