Renal arteriovenous fistulae (AVF) are a rare condition that can be acquired, congenital or idiopathic. Idiopathic AVF are the rarest type of renal AVF. Traditionally, renal AVF were treated with surgery, but the mainstay of treatment has shifted to an endovascular approach by coil embolization. Embolization procedures are often difficult, secondary to the ‘high flow’ of the AVF, and there is a substantial risk of distal embolization of the coils. We present the case of a 63-year-old hypertensive woman who presented with pain in the right flank, of 7 days’ duration, with no other genitourinary or gastrointestinal complaints. She had undergone hysterectomy 7 years ago. CT abdomen, and subsequently CT angiography, of her abdomen were suggestive of giant right renal AVF. We successfully embolized this idiopathic renal AVF with an Amplatzer vascular plug.
