title: Mycotic aortocaval fistula: efficient evaluation by bolus-chase MR angiography.
abstract: Aortocaval fistula (ACF) is a rare but life-threatening condition. This case report describes the use of bolus-chase gadolinium-enhanced 3D magnetic resonance angiography (MRA) to provide an efficient evaluation of a patient with ACF associated with a mycotic abdominal aortic aneurysm. This case highlights the ability of bolus-chase MRA to provide both the specific diagnosis of ACF as well as the information necessary for extra-anatomic arterial bypass. Bolus-chase MRA is a promising method for the evaluation of patients with this disease entity.
